Barnikal, Screeching Kraken

Companion — Your starting deck contains
Leviathans, Krakens, Merfolk, and Zombie
creatures. (If this creature is your chosen companion,
you may cast it once from outside the game.)
Whenever a Leviathan, Kraken, Merfolk, or
Zombie enters the battlefield under your control,
put a +1/+1 and a Deathtouch counter on that
creature. Barnikal deals 1 damage to any target.
