Hexerei
Bis zum Ende des Zuges erhält eine Kreatur deiner Wahl +1/+1 für jede Kreatur, die du kontrollierst, und verursacht Trampelschaden. Sie muss in diesem Zug geblockt werden, falls möglich.
If the creature attacks, the defending player must assign at least one blocker to it if that player controls any creatures that could block it. Other creatures may also block it, block other creatures, or not block at all.
Use the number of creatures you control as King Harald's Revenge resolves to determine how big the power and toughness boost is.
