Apprentice Biomancer

At the beginning of each upkeep, if Apprentice Biomancer has less than 8 +1/+1 counters on it, you may pay {g/u}. If you do,
put a +1/+1 counter on it.
As long as Apprentice Biomancer has 8 or
more +1/+1 counters on it, it has trample
and is an octopus in addition to its other
types.
