Conjuro
Hasta el final del turno, las criaturas que controlas obtienen +2/+2 y ganan "Siempre que esta criatura haga daño de combate a un jugador o planeswalker, destruye el artefacto o encantamiento objetivo que controla el jugador defensor".
Storm the Citadel affects only creatures you control at the time it resolves. Creatures you begin to control later in the turn won’t get +2/+2 or gain the triggered ability.
If a creature is attacking a planeswalker, the controller of the planeswalker is the defending player.
