Rin and Seri, cats and dogs 🐶😻

Rin and Seri, Inseparable leads a Cat-and-Dog tribal token deck that turns each creature spell into an extra token, then builds a wide board supported by anthem effects like King of the Pride, Regal Caracal, and Jetmir, Nexus of Revels. The deck primarily wins by overwhelming opponents in combat with a huge token army, especially after Camaraderie, Titanic Ultimatum, or Mirror Entity, while Rin and Seri’s activated ability converts your Dog count into direct damage and your Cat count into life gain. A key synergy is casting Cats and Dogs to trigger the commander repeatedly, then multiplying the resulting board with Second Harvest and protecting it through cards such as Heroic Intervention or And They Shall Know No Fear.
