  • If there are multiple creatures that have "blocks if able", the defending player can choose which creature blocks.
  • If there is a creature that "can't be blocked" and "blocks if able", the "can't be blocked" takes precedence.
  • If a "blocks if able" creature gets "can't block", "can't block" takes precedence.
  • Very few cards give "block if able" to your opponent's creatures, and are mostly among the Light, Darkness and Nature civilizations. The ability also has no function if your opponent doesn't use creatures that have the Blocker keyword.
    • Among these, Iron Rose, Full Metal gives the Blocker ability to your opponent's creatures as well as forcing them to "block if able".
