Gerrit, Competetive Mage

Wisdom
Gerrit, Competetive Mage's power/toughness is
equal to the highest power/toughness among creatures on the battlefield.
Gerrit, Competetive Mage has trample as long as another creature on the battlefield has trample.
The same is true for flying, lifelink, haste,
vigilance, first strike, double strike, menace and
deathtouch.
