Cloud, Punisher Mode

Aura spells that target Cloud cost {1} less to cast.

At the beginning of combat on your turn, if Cloud
has power 7 or greater, you may sacrifice an aura
attached to Cloud, if you do Cloud deals 3 damage
to each creature your opponents control.

When Cloud attacks, look at the top X cards of your
library where X is the number of auras attached to
Cloud. Put one into your hand and the rest on top
in any order.
