Overcharged Amalgam

Overcharged Amalgam’s exploit ability can’t target mana abilities. An activated mana ability is one that could add mana as it resolves, doesn’t have a target, and isn’t a loyalty ability. A triggered mana ability is one that could add mana as it resolves and triggers based on an activated mana ability.

If you counter a delayed triggered ability that triggers 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.

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

Activated abilities are written in the form “[Cost]: [Effect].” Some keyword abilities, such as equip and crew, are activated abilities and will have colons in their reminder texts.

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