Evolution Apparatus

Whenever you draw a card by a card effect or
put a +1/+1 counter on a creature you control,
put a +1/+1 counter on Evolution Apparatus.
It can't gain counters by its own effect.
If there are 4 counters on Evolution Apparatus,
it can't gain additional counters and you may pay
{g/u}. If you do, distribute its +1/+1 counters on
creatures you control. If you distribute them on
at least 3 different creatures, put a +1/+1 counter
on Evolution Apparatus and draw a card.
