On the other hand, Life and Limb also depends upon Conspiracy because applying Conspiracy first makes Gutter Skulk a Saproling, increasing the number of permanents Life and Limb applies to.

What will total cost be?
Because applying Urborg after Blood Moon changes whether Urborg’s ability exists, it is dependent upon Blood Moon and Blood Moon applies first.

These are the layers in order: Type, subtype, and supertype-changing effects. Any effect which doesn’t fall under the other 5 layers.

Wizards cleverly reworded this into a text-changing effect, which means it applies afterward in layer 3. While you're still learning the process above, it helps to have a way to layout the effects in a way to make them easy to visualize. But there’s no reason to be intimidated! The Gutter Skulk, though a Saproling now, will remain 2/2. What are the characteristics of her permanents? That means they are all applied after layer 7 in timestamp order. I've also found these very useful to print out for attendees if you're planning on running a seminar on this topic. All nonbasic lands are Mountains. When we talk about applying effects in 'timestamp order' we mean to apply the oldest effect first, then the next oldest and so on.

The application of continuous effects as described by the layer system is continually and automatically performed by the game. Any effect which would change the text of the object you’re evaluating.

Unless it says otherwise, all objects are face up and untapped.Example 1, The following effects are applied in chronological order to your Benalish Cavalry, The following effects are applied in chronological order to your Gray Ogre with a +1/+1 counter on it, Example 3 (Warning: Beyond the realms of realism)

Then Conspiracy would apply and make Gutter Skulk a Saproling. In layer 5, Life and Limb would make the Forest green.

Any ability or spell that generates this type of effect should contain the word ‘Control’. Note: If either Gutter Skulk or Forest wasn’t on the battlefield, there would be no dependency loop. Both effects are applied in the same layer (or sub-layer). When these continuous effects start to pile up, we need to know how they interact. For instance, if Maro was hit by such an effect, its power and toughness would be undefined. The following effects are applied in chronological order to your Exalted Angel with a +1/+1 counter on it.

The active player determines the timestamp of objects entering a zone at the same time. The effects from static abilities on objects that stay in play live in this layer. A: These continuous effects don’t affect the characteristics of any objects. During my time as a DCI Judge, I've always found this topic challenging. Continuous Effects.

That means the effect will apply even to damage from creatures that weren’t on the battlefield when the continuous effect began. In layer 7, there are two competing effects trying to set Humility’s p/t; Humility wants it to be 1/1, an Opalescence wants it to be 4/4. Don’t be intimidated!

on November 26, 2007. In fact, all of this can be found in the comp rules (rule 418.5), but in a vastly condensed form. In this case, Humility entered the battlefield first, so it becomes a 1/1, then ends up a 4/4 after Opalescence applies. If you have any questions about this topic or feedback on this article, I'd welcome it (nick@dcijudge.co.uk). Introductions are in order – Official names for stuff, Just my type – Types, subtypes, and supertypes, Let me Spell it out for you – How to cast a spell, Learning how to count – Converted mana costs, Swimming in the Mana Pool – Mana abilities, TOADS – Power- and toughness-changing abilities, What you thought you knew – Tournament trivia, Enters the battlefield replacement effects, Investigations | GP Cleveland Tournament Report, Updated!

It defines one or more of the following: colour, subtype, power or toughness. Why can’t we just apply all the continuous effects in timestamp order?

What is the shapeshifter’s p/t? The most common issue is mistakenly identifying an ability-adding effect as a text-changing effect. Continuous effect A is dependent upon continuous effect B if they are applied in the same layer (and sublayer) and applying B before A would: Change the set of things that A applies to, Change how A affects any of those things, or.

Effects from static abilities that modify power and/or toughness but don’t set power and/or toughness to a specific number or value, In order to be placed in 6d, an effect must originate from a static ability and modify but not set P/T. A very common mistake is to place effects here that should be placed in Layer 6d, or vice-versa. Because continuous effects apply continuously, there’s no point at which the bear is on the battlefield that it’s not getting -1/-1. Sentences that evoke vivid images, particularly humorous, violent, or sexualized ones tend to work well because they’re easier to remember. Then Life and Limb would apply and make both Gutter Skulk and Forest into Creature Land – Saproling Forests. If a creature becomes white, it gets this bonus; a creature that stops being white loses it. The goal of the continuous effects system is to make it so the answer to any continuous effects question is what we would intuitively expect as often as possible.

Finally, in an attempt to defeat my demon, I decided to study the topic intricately and write an article that will hopefully be helpful to both judge and non-judge alike.

A: Cost increasing effects apply before cost reducing effects, and cost-setting effects (which, to date, includes only Trinisphere) are applied last. If you’ve been through my L1 prep material, you’re already familiar with my mnemonic TOADS, which stands for Tarmogoyf, Omnibian, Auger Spree, Decree of Savagery, Strange Inversion for the sublayers.


She wants to cast a Frogmite. Each object has a timestamp, which marks the time it entered its current zone. You might not ever say that they’re easy, but after becoming familiar with the system that governs their interactions, they should at least make sense.

Unless the Oracle wording or CR definition of the effect includes the word “text” (like Mind Bend, Volrath’s Shapeshifter, or the overload mechanic do), it isn’t a text-changing effect. An effect can be said to depend upon another effect if: An effect that would apply in two or more different layers is broken into parts and each part applies in the relevant layer. Note: Have you ever wondered why all the cards that make creatures lose all abilities always set the base p/t also? Q: Amy controls a Spellbook and a Recycle, and her opponent controls a Gnat Miser.

These should be easy to spot, but they’re often thrown in as part of a larger ability. Applying Urborg first doesn’t change anything about what Blood Moon will do, but applying Blood Moon before Urborg will make Urborg into a Mountain, removing its abilities. So: Benalish Cavalry - Creature - Human Knight – Flanking – 2/2, Becomes:Benalish Cavalry – Creature – Frog – 6/6, Becomes:Gray Ogre – Creature – Ogre – 1/4.

Objects that phase out/in do not receive a new timestamp. Determine which layer it should be assigned to.

You have a starting value (your original object), a number of values to combine in some way (your effects) and hopefully at some point an answer. A: Both of Life and Limb and Conspiracy try to apply in layer 4, so we check for dependencies. Finally Trinisphere checks the cost, sees it is less than 3, and sets it to that much. Effects that do any of the following things apply in the order dictated by the layers.

How big are the other creatures? Any effect which would copy values onto the object you’re evaluating. As you read through the examples here, before reading the answers, think about what you would expect the answer to be if you were playing a game and this came up. Example: If you control. If a continuous effect begins to apply in one layer or sublayer, all parts of that effect will apply to the same set of objects in each subsequent layer or sublayer, even if the set of objects it wants to apply to changes or it loses the ability generating that effect during the process. Before we can correctly assign effects to layers, we've got to be able to understand a few basic concepts: A characteristic-defining ability is an ability that has the following qualities: Any ability that has these three qualities is a Characteristic-Defining ability (CDA). Example: Master Thief has the ability “When Master Thief enters the battlefield, gain control of target artifact for as long as you control Master Thief.” If you lose control of Master Thief before the ability resolves, it does nothing, because its duration—as long as you control Master Thief—was over before the effect began.

From the glossary of the Comprehensive Rules (September 25, 2020—Zendikar Rising), From the Comprehensive Rules (September 25, 2020—Zendikar Rising). A common phrase at such an occasion is "This isn't in the rule book!" Sometimes an effect can depend upon another effect. For example, all copy effects always apply before all control-changing effects. These effects are applied after all other continuous effects have been applied.

Nothing is more intricately intertwined with the reputation of a rules expert than a solid knowledge of continuous effects. Goblin King enters play under your control. These are important because they're applied before other abilities of a similar type. It’s because some creatures depend on their abilities to set their power and toughness.
