Mitchaw Warmaster

Plumage 2 - {w}{u} (You may pay an additional {w}{u} as you cast this spell. If you do, create two 1/1
white and blue Bird creature tokens with flying as this
spell resolves.)
Flying, vigilance
Whenever a creature an opponent controls
attacks, if you're the defending player, put a
+1/+1 counter on each other creature you control
with flying unless that creature's controller pays {2}.
