Kostima, Aspiring Lich

Kostima gets +2/+2, has protection from
creatures, and isn't a Human as long as there
are two or more lich counters on him.
At the beginning of your end step, you may
pay 1 life. If you do, put a lich counter on
Kostima.
{b}, Remove a lich counter from Kostima: Target creature gets -2/-2 until end of turn.
