Thrawn, Grand Admiral

Whenever you cast a noncreature spell, amass Stormtroopers X, where X is that spell's mana value. (Put X +1/+1 counters on an Army you control. It's also a Stormtrooper. If you don't control an Army, create a 0/0 black Stormtrooper Army creature token first.)
Imperials and Stormtroopers you control have ward {2}.
