Mobilization

Cumulative upkeep {r/w} (At the beginning of your
upkeep, if this permanent is on the battlefield, put an
age counter on this permanent. Then you may
pay {r/w} for each age counter on it. If you don't,
sacrifice it.)
At the end of your turn, put X 1/1 white soldier
in play, where X is equal to 1 plus the number of
Age counters on Mobilization.
