"Come, Koma, and reclaim what you lost! Or does the great serpent fear a rematch?"

Foundations

Fynn, the Fangbearer

Deathtouch (Any amount of damage this deals to a creature is enough to destroy it.)
Whenever a creature you control with deathtouch deals combat damage to a player, that player gets two poison counters. (A player with ten or more poison counters loses the game.)

"I always said I had a score to settle with that serpent. I'm a man of my word."
