Consign to Memory

A copy of a spell can be countered like any other spell, but it must be countered individually. Countering a spell with replicate won't affect the copies.

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