Format: Commander

Commander: Rin and Seri, Inseparable

Bracket: 3

Deck overview

Rin and Seri, Inseparable is the engine of a Dog/Cat changeling token deck. The primary plan is to land the commander early, then chain cheap changeling spells: each changeling spell is both a Dog and a Cat, so it creates one Cat token and one Dog token. Token doublers and end-step copy effects rapidly widen the board, while Mirror Entity, Prava of the Steel Legion, and Roar of Resistance turn that board into one massive lethal swing. The commander's activated ability serves as extra reach and life gain. No hidden commander exists; Prava is support, not a second commander.
