Zudros, Martial Paragon

Whenever another creature you control attacks,
put a flying counter on Zudros if that creature
has flying. The same is true for first strike,
double strike, deathtouch, haste, hexproof, indestructible, lifelink, menace, protection,
reach, trample, and vigilance.
{1}{w/u}, Remove a counter from Zudros: Put the
same kind of counter on another target creature
you control.
