Heir of the Ancient Fang
Creature — Snake Samurai
This creature enters with a +1/+1 counter on it if you control a modified creature. (Equipment, Auras you control, and counters are modifications.)
On the last day of a Jukai agent's training, they are bequeathed a powerful relic blessed by the kami.
