Kiryu Jilves, Gaia's Roar:
This card is put into the battle zone tapped. When this creature is put into the battle zone, all of your creatures gain "Slayer" and "Speed Attacker" until the end of this turn. During this turn, when your creatures are destroyed, they are put into the mana zone instead of the graveyard.
When anger, grief, and joy come together, it becomes a roar that make all who listen to it tremble in fear.
