John, Infintely Scaling

During your upkeep add a +1/+1 counter to
each John creature you control.
During your end step, proliferate.
If a John creature you control has at least
3 counters it has first strike, if it has at least
5 counters it has menace, and if it has at least
7 counters it has trample.
