Nakarkos, the Corpse Dragon

Nakarkos enters tapped with nine stun counters on
it. (If a permanent with a stun counter would become untapped, remove one from it instead.)

Whenever you draw a card during an opponent's turn, create a 1/1 blue Tentacle creature token.

Whenever a tentacle you control dies, untap up to
one target Kraken and put a stun counter on up to one other target nonland permanent.
