Training Grounds

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 {X}{R} 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.

If an activated ability of a creature you control costs no generic mana to activate (for example, if it costs {R}{R}, it costs {0}, or it costs only nonmana actions such as {T} or "Sacrifice a creature"), Training Grounds simply won't affect it. In particular, it won't increase the cost to include a mana payment of {1}.

Training Grounds won't affect the part of an activation cost represented by colored mana symbols or snow mana symbols. It also won't affect nonmana parts of an activation cost, if there are any.
