Rulings
  • WotCJan 25, 2019

    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.

  • WotCJan 25, 2019

    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}.

  • WotCJan 25, 2019

    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.

  • WotCJan 25, 2019

    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.
