  • Activated abilities contain a colon. They’re generally written “[Cost]: [Effect].” Some keyword abilities are activated abilities and will have colons in their reminder text. Triggered abilities (starting with “when,” “whenever,” or “at”) are unaffected by the cost reduction ability of Biomancer’s Familiar.
  • An ability that has only one generic mana and some amount of other mana symbols in its activation cost will have its cost reduced by {1}.
  • Biomancer’s Familiar affects only abilities of creatures you control on the battlefield. The costs of activated abilities of creature cards that work in other zones (such as cycling) won’t be reduced.
  • The last ability of Biomancer’s Familiar doesn’t add or remove any counters. It just lets the creature adapt despite already having +1/+1 counters on it.

    Rules

  • Activated abilities contain a colon. They're generally written “[Cost]: [Effect].” Some keyword abilities (such as equip) are activated abilities and will have a colon in their reminder text.
  • Any choices made when the spell or ability resolves won't have been made yet when it's copied. Any such choices will be made separately when the copy resolves. Most notably, if a triggered ability asks you to pay a cost (such as that of Leyline Tyrant), you pay that cost for the copy if you wish to have it paid.
  • If a permanent spell is copied, it's put onto the battlefield as a token as the spell resolves rather than putting the copy of the spell onto the battlefield. The rules that apply to a permanent spell becoming a permanent apply to a copy of a spell becoming a token.
  • If an ability is linked to a second ability, copies of that first ability are also linked to that second ability. If the second ability refers to “the exiled card,” it refers to all cards exiled by the first ability and the copy. For example, if Fiend Hunter's enters-the-battlefield ability is copied and two creatures are exiled, they both return when Fiend Hunter leaves the battlefield.
  • If the spell or ability has damage divided as it was put onto the stack, the division can't be changed, although the targets receiving that damage still can. The same is true of spells and abilities that distribute counters.
  • If the spell or ability that's copied has an X whose value was determined as it was cast or activated, the copy will have the same value of X.
  • If the spell or ability that's copied is modal (that is, it says “Choose one —” or the like), the copy will have the same mode. A different mode can't be chosen. This doesn't apply to copying a permanent spell with a modal enters-the-battlefield triggered ability, but it does apply to copying that ability.
  • Lithoform Engine can copy any spell or ability on the stack, not just one with targets. If a permanent spell is copied, new targets can't be chosen for it, if it has any (perhaps because it's an Aura or a mutating creature spell).
  • Lithoform Engine's first ability targets an activated or triggered ability that is on the stack and creates another instance of that ability on the stack. It doesn't cause any object to gain an ability.
  • The copy is created on the stack, so it's not “cast” or “activated.” Creating the copy won't cause abilities that trigger when a player casts a spell or activates an ability to trigger. Abilities that say that a triggered ability triggers additional times won't apply to copying a triggered ability.
  • The copy will have the same targets as the spell or 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).
  • The copy will resolve before the original spell or ability does.
  • The source of the copy from Lithoform Engine's first ability is the same as the source of the original ability.
  • The token that a resolving copy of a spell becomes isn't said to have been “created.”
  • 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.
  • You can't choose to pay any alternative or additional costs for the copy. However, effects based on any alternative or additional costs that were paid for the original spell are copied as though those same costs were paid for the copy. Most notably, if the original spell was kicked, the copy is kicked.

    Rules

  • 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 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 takes the total cost to activate a creature's activated ability into account, not just the cost printed on it. For example, Urabrask has an activated ability that costs {R}, and Suppression Field says "Activated abilities cost {2} more to activate unless they're mana abilities." Since activating Urabrask's activated ability would now cost {2}{R}, Training Grounds reduces that cost back to {R}.
  • 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.

    Rules

  • If a creature with an {Q} ability hasn't been under your control since your most recent turn began, you can't activate that ability, unless the creature has haste.
  • If the permanent is already untapped, you can't activate its {Q} ability. That's because you can't pay the "Untap this permanent" cost.
  • When you activate an {Q} ability, you untap the creature with that ability as a cost. The untap can't be responded to. (The actual ability can be responded to, of course.)
