Training Grounds

Training Grounds Rulings

• Oct 2, 2025

  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 affects only creatures you control on the battlefield. The costs of activated abilities that work in other zones (such as cycling or unearth) won't be reduced.

  Training Grounds can reduce the amount you pay for a creature's activated ability cost that includes {X}. For example, Drana, Kalastria Bloodchief has an activated ability that costs {X}{B}{B}. If you control Training Grounds and you activate the ability with X equal to 5, you'll have to pay only {3}{B}{B}. This is true even if the ability states that {X} must be paid with a certain color of mana, as Crimson Hellkite's ability does.

  Training Grounds can reduce the part of an activation cost represented by generic mana symbols down to nothing, as long as it still costs at least one mana. For example, if an activation cost is {2}{G}, you'd have to pay only {G}. If an activation cost is {2}, though, you'd still have to pay {1}.

  Training Grounds reduces the generic mana in waterbend costs for activated abilities. It will not reduce waterbend costs that are additional costs for casting spells.
