A +1/+1 counter value deck. Marchesa gives every creature dethrone, so attacks hand out counters, and any creature that dies with a counter comes back at the next end step. The rest of the list keeps putting and spreading counters through proliferate, riot, backup and combat-damage growth, then cashes them in. Counters become evasion, doubled damage, card draw and graveyard recursion. Sacrifice outlets and board wipes turn Marchesa's return trigger into repeatable value, since only the deck's own countered creatures come back. How it wins: Countered creatures get unblockable or menace attacks, extra combats and doubled damage to beat opponents down, backed by burn from counter placement and two infinite combos: All Will Be One with The Red Terror, and Spark Double with Murderous Redcap and Ashnod's Altar. Key roles: - Counter placement and proliferate: These spread and multiply +1/+1 counters across the board each turn, switching on Marchesa's recursion and every counter payoff (Andúril, Narsil Reforged, Inexorable Tide, Unspeakable Symbol). - Evasion and extra combat: Counter-bearing creatures become hard or impossible to block and can attack twice, which fuels dethrone and combat-damage growth (Herald of Secret Streams, Hagra Constrictor, Akki Battle Squad). - Damage amplification and burn: Counters double creature damage or turn each placement into direct damage. All Will Be One and The Red Terror loop into infinite damage (Uncivil Unrest, Raphael, the Muscle, All Will Be One). - Sacrifice and recursion engine: Altars and self-returning creatures exploit Marchesa's end-step return, persist and undying for mana and repeated enter triggers. Spark Double copying Murderous Redcap with Ashnod's Altar loops infinitely (Ashnod's Altar, Murderous Redcap, Flayer of the Hatebound). - Card advantage from counters and deaths: Counters landing on creatures and creatures dying or re-entering keep the hand full (Danny Pink, Skullclamp, Grim Haruspex). - Board wipes and reset: Sweepers clear opposing boards while countered creatures return under Marchesa, and counters lost to removal are banked for later (Blasphemous Act, The Meathook Massacre, The Ozolith).
