Trazyn the Infinite + Retrofitter Foundry + Prismatic Geoscope

Trazyn the Infinite

Retrofitter Foundry

Prismatic Geoscope

How it works

1. Activate Trazyn using Prismatic Geoscope's ability by tapping it, adding at least four mana of any color.
2. Activate Trazyn using Retrofitter Foundry's ability by paying 3, untapping it.
3. Repeat.

With Trazyn the Infinite on your battlefield, its Prismatic Gallery ability absorbs the secrets of your graveyard, granting it access to every activated ability sitting among your fallen artifacts. This allows Trazyn to channel Prismatic Geoscope for a flood of colored mana, tapping and untapping itself endlessly by adopting Retrofitter Foundry's untap ability. Because Trazyn inherits these tools without needing them on the board as separate permanents, you can cycle through this loop to generate infinite mana, a mountain of creature tokens, and boundless entry, death, and sacrifice triggers.
