Whenever a player casts a spell, that player mills four cards.
Whenever chaos ensues, you may exile a creature card from your graveyard. If you do, create a white Aura enchantment token attached to target creature you control with enchant creature and “Enchanted creature gains all activated and triggered abilities of the exiled card and gets +X/+Y, where X is equal to the exiled card's power and Y is equal to its toughness.”
