Obi Wan Kenobi, Jedi General

First Strike, Vigilance, Reach

When Obi Wan enters the battlefield, create X 1/1 White and Blue clone trooper creature tokens where
X equals the greatest toughness among other creatures you control.

Whenever a Jedi or Clone you control blocks an attacking creature, they gain +X/+X until end of turn where X is Obi Wan's toughness.
