Orcish Battlemage

Whenever you cast your first instant or sorcery spell each turn, the Ring tempts you.

Whenever the Ring tempts you, if you chose Orcish Battlemage as your Ring-bearer, amass Orcs 1. (Put a +1/+1 counter on an Army you control. It's also an Orc. If you don't control an Army, create a 0/0 black Orc Army
creature token first.)
