Vrasky, Spark of Hope

Flying, trample
When Vrasky, Spark of Hope enters the
battlefield, you may search your library for a
Dragon card with mana value 3 or less, put it
onto the battlefield, then shuffle.
Whenever a Dragon you control attacks, you may
untap it and remove it from combat. When you
do, it deals X damage to target player, where X is
it's power. Activate only once each turn.
