原文Training Grounds won't affect a cost that isn't the cost to activate a creature's activated ability. For example, it won't affect Flameblast Dragon's cost, since that's a cost paid when a triggered ability resolves, and it won't affect a kicker cost, since that's an additional cost to cast a spell. Activated ability costs appear before a colon (:) in a card's rules text, or, in the case of some keywords, before a colon in reminder text.
