Agrus Kos copies activated abilities and triggered abilities targeting him for 1 and a red or white mana; Soulbright Flamekin's activations bank eight red each cycle, and Felidar Guardian's blink trigger resets both Soulbright Flamekin and Mnemonic Wall. Mnemonic Wall rebounds Deflecting Swat from the graveyard each loop, and Deflecting Swat redirects leftover Felidar Guardian triggers back to Agrus Kos for free, closing the circuit. The combo is dense and sequencing-dependent — one missed priority hold or a stifle on Mnemonic Wall's ETB collapses the whole chain.

Variations

Cheaper, tighter, alternate lines

Archaeomancer substitutes for Mnemonic Wall as the spell-recurrence piece with an identical ETB, though it costs one less mana and has a smaller body. The loop generates infinite red mana but needs a sink to close — Purphoros, God of the Forge converts infinite ETBs into lethal damage without adding a cast step, and Aetherflux Reservoir closes on storm count alone.
