Necrotic Ooze

Wizards of the Coast 1 Jan 2011

If an activated ability of a card in a graveyard references the card it's printed on by name, treat Necrotic Ooze's version of that ability as though it referenced Necrotic Ooze by name instead. For example, if Cudgel Troll (which says "{G}: Regenerate Cudgel Troll") is in a graveyard, Necrotic Ooze has the ability "{G}: Regenerate Necrotic Ooze."

Wizards of the Coast 1 Jan 2011

Necrotic Ooze gains only activated abilities. It doesn't gain keyword abilities (unless those keyword abilities are activated), triggered abilities, or static abilities.

Wizards of the Coast 1 Jan 2011

Activated abilities contain a colon. They're generally written "[Cost]: [Effect]." Some keywords are activated abilities; they have colons in their reminder text.

Scavenging Ooze

Wizards of the Coast 23 Jun 2020

If the target card is an illegal target when the ability tries to resolve, it won't resolve and none of its effects will happen. No +1/+1 counter will be put on Scavenging Ooze and you won't gain life. Notably, this means that if you activate Scavenging Ooze's ability multiple times targeting the same creature card, only the first instance of the ability to resolve will have any effect.

The Mimeoplasm

Wizards of the Coast 22 Sep 2011

The two creature cards may come from the same graveyard or different graveyards.

Wizards of the Coast 22 Sep 2011

You can't choose to exile just one creature card.

Wizards of the Coast 22 Sep 2011

You choose which one The Mimeoplasm is copying and which one determines how many +1/+1 counters are placed on The Mimeoplasm as The Mimeoplasm enters.

Wizards of the Coast 22 Sep 2011

Treat The Mimeoplasm as though it were the creature card it's copying entering the battlefield. Any "As [this card] enters," "[This card] enters with," and "When [this card] enters" abilities of that creature card will work.

Wizards of the Coast 22 Sep 2011

Specifically, if The Mimeoplasm as a copy of a creature card that enters the battlefield with a number of +1/+1 counters, The Mimeoplasm will enter with those +1/+1 counters and +1/+1 counters equal to the power of the other exiled card.

Voidslime

Wizards of the Coast 12 Jan 2024

Activated abilities are written in the form "[Cost]: [Effect]." Some keyword abilities, such as equip, are activated abilities and will have colons in their reminder texts. Loyalty abilities of planeswalkers are activated abilities.

Wizards of the Coast 12 Jan 2024

Triggered abilities use the word "when," "whenever," or "at." They're often written as "[Trigger condition], [effect]." Some keyword abilities, such as afterlife, are triggered abilities and will have "when," "whenever," or "at" in their reminder text.

Wizards of the Coast 12 Jan 2024

An activated mana ability is one that adds mana as it resolves, doesn't have a target, and isn't a loyalty ability. A triggered mana ability is one that adds mana and triggers on an activated mana ability.

Wizards of the Coast 12 Jan 2024

If you counter a delayed triggered ability that triggered at the beginning of the "next" occurrence of a specified step or phase, that ability won't trigger again the following time that phase or step occurs.

Wizards of the Coast 12 Jan 2024

Abilities that create replacement effects, such as a permanent entering the battlefield tapped or with counters on it, can't be targeted. Abilities that apply "as [this creature] enters the battlefield" are also replacement effects and can't be targeted.
