The Imperial March

At the beginning of your upkeep, you lose 1 life and amass Stormtrooper 1. (Put a +1/+1 counter on an Army you control. It's also a Stormtrooper. If you don't control an Army, create a 0/0 white Stormtrooper Army creature token first.)
Whenever a Stormtrooper token you control with power 6 or greater attacks, it gains lifelink until end of turn.
