Barrage of Strikes

Play Barrage of Strikes only during your turn and only during combat.
If you control a commander, you may cast this spell for {1}{r}{w}.
Put a +1/+1 counter on target attacking creature you control and untap it. It gains double strike until end
of turn. After this phase, there is an additional combat phase.
