Trumpet Blast

Instant, 2R (3)
Attacking creatures get +2/+0 until end of turn.
Keldon warriors don't need signals to tell them when to attack. They need signals to tell them when to stop.

• 10/4/2004: Only affects creatures which are attacking at the time it resolves.
• 10/1/2009: An "attacking creature" is one that has been declared as an attacker this combat, or one that was put onto the battlefield attacking this combat. Unless that creature leaves combat, it continues to be an attacking creature through the end of combat step, even if the player it was attacking has left the game, or the planeswalker it was attacking has left combat.
• 10/1/2009: Even though Trumpet Blast affects only attacking creatures, the bonus will remain for the rest of the turn.
• 10/1/2009: If Trumpet Blast is cast before attackers are declared or after combat ends, it won't do anything.
