Activated abilities contain a colon. They’re generally written “[Cost]: [Effect].” Some keyword abilities (such as boast) are activated abilities and will have colons in their reminder text. An activated mana ability is one that produces mana as it resolves, not one that costs mana to activate.

Copying abilities doesn’t cause magecraft abilities to trigger.

The copy will have the same targets as the ability it’s copying unless you choose new ones. You may change any number of the targets, including all of them or none of them. If, for one of the targets, you can’t choose a new legal target, then it remains unchanged (even if the current target is illegal).

If the ability is modal (that is, it has a bulleted list of modes), the copy will have the same mode(s). You can’t choose new ones.

If the ability has {X} in its activation cost, the copy has the same value of X.
