Poppet Stitcher // Poppet Factory + Mana Echoes + Phyrexian Altar + Mystic Speculation

Poppet Stitcher // Poppet Factory

Mana Echoes

Phyrexian Altar

Mystic Speculation

How it works

1. Cast Mystic Speculation with buyback by paying 2.
2. Poppet Stitcher triggers, creating a 2/2 Zombie creature token.
3. When the Zombie enters the battlefield, Mana Echoes triggers, adding C for each Zombie you control.
4. Resolve Mystic Speculation, causing you to scry 3 and returning Mystic Speculation to your hand.
5. Activate Phyrexian Altar by sacrificing the Zombie, adding .
6. Repeat.
7. If you control two or more Zombies as the combo begins, this combo nets infinite colorless mana.

This ingenious loop hinges on a clever feedback loop between spellcasting and token generation: casting Mystic Speculation with buyback triggers Poppet Stitcher to produce a Zombie token, which immediately feeds Mana Echoes to generate an escalating surplus of colorless mana. Meanwhile, Phyrexian Altar provides the crucial sacrifice outlet to clear away the decayed token while recycling colored mana to keep the buyback cost covered. Because Mystic Speculation continuously returns to your hand, you can repeat this sequence indefinitely to fuel your mana pool, sculpt your library with infinite scries, and trigger endless deaths.
