Seven-Tail Mentor turns every Samurai or Warrior you cast into a keyword-buffet — slapping your choice of flying, first strike, vigilance, trample, lifelink, or haste onto any creature in your hand before it even hits the board. The cost is a three-mana 2/2 with no immediate impact, so you're banking on the keyword-granting ability firing repeatedly to justify the slot. In the right shell it earns that slot; outside it, it's a build-around that does nothing alone.

Raiyuu, Storm's Edge
Raiyuu, Storm's Edge cares deeply about a single Samurai or Warrior attacking unblocked, and Seven-Tail Mentor is the enabler that slaps evasion — flying, trample, or the keyword that clears the path — onto whatever attacker Raiyuu is backing that turn, turning each extra combat into a guaranteed trigger.

Seven-Tail Mentor is a Commander card in practice — the Samurai and Warrior tribal density required to fire the ability turn after turn only exists in a 99-card singleton shell built around it. In competitive 60-card formats like Modern or Pioneer, a three-mana 2/2 that requires a specific creature type in hand is far too slow and conditional to see serious play. Pauper is legal but the same logic applies — the common-slot competition is brutal and tribal keyword-granting at this rate doesn't clear the bar. Stick to Commander, specifically any Boros or Mardu Samurai build where Seven-Tail Mentor slots naturally into a tribal curve.

Price Context
Current price
$0.17 bulk tier
At $0.17, Seven-Tail Mentor is pure bulk — grab a copy out of any bargain bin without a second thought. Demand is narrow enough that this price is stable; it's not climbing unless a pushed Samurai or Warrior commander causes a spike in the archetype.
