Vesuvio, Simic Aquamancer

Whenever a creature you control adapts, create a 1/1 blue Spirit creature token with flying. Then, if you control five or more creatures, draw a card.
Nontoken creatures you control have
''{u}{g}: Adapt 1. (If this creature has no +1/+1 counters on it, put a +1/+1 counter on it.''
