Stormtrooper Ranks

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