Deluge of Ash

All creatures get -2/-0 until end of turn.
Tap all creatures that attacked this turn. They
don't untap during their controller's next untap step.
"A surprisingly clever battle tactic of the Grawn Brood is catapulting barrels of ash into the oncoming forces. What is worse than fighting in full steel, against an agile opponent? Not being able to breathe or see." -Zhivagan Tactician
