Exploit (When this creature enters the battlefield, you may sacrifice a creature.)
When Overcharged Amalgam exploits a creature, counter target spell, activated ability, or triggered ability.
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.
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.
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.
Overcharged Amalgam's exploit ability can't target mana abilities. An activated mana ability is one that could add mana to a player's mana pool as it resolves, doesn't have a target, and isn't a loyalty ability. A triggered mana ability is one that adds mana to a player's mana pool and triggers based on an activated mana ability.
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.
