Sylas, the Unshackled

Hijack - {4}: Sylas, the Unshackled copies the text
box of another target non-Aura, non-equipment permanent and adds it to his text box until end of
turn. If an activated or triggered ability of Sylas' that
was copied this turn would activate or trigger, that ability triggers an additional time. If the target is a creature, you may have Sylas' power and toughness
become the power and toughness of that creature
until end of turn.
