Chasm Skulker (Surge Foil) [FINAL FANTASY Commander]

Whenever you draw a card, put a +1/+1 counter on this creature.

When this creature dies, create X 1/1 blue Squid creature tokens with islandwalk, where X is the number of +1/+1 counters on this creature. (They can't be blocked as long as defending player controls an Island.)
