Summon: G.F. Cerberus + Biovisionary + Repudiate // Replicate

Summon: G.F. Cerberus

Biovisionary

Repudiate // Replicate

How it works

1. At the beginning of your precombat main phase. Summon: G.F. Cerberus triggers, putting a lore counter on it and triggering its third chapter ability, copying the next instant or sorcery spell you cast twice.
2. Cast Replicate by paying its mana cost, targeting Biovisionary.
3. Summon: G.F. Cerberus triggers, copying Replicate twice, with the copies targeting Biovisionary.
4. Resolve all Replicates, copying Biovisionary three times.
5. At the beginning of your end step, each Biovisionary triggers. Resolve the first trigger, causing you to win the game.
