Scuttling Sliver + Trazyn the Infinite + Amoeboid Changeling + Nyx Lotus

Scuttling Sliver

Trazyn the Infinite

Amoeboid Changeling

Nyx Lotus

How it works

1. Activate Amoeboid Changeling by tapping it, causing Trazyn to become a Sliver until end of turn.
2. Activate Trazyn using Nyx Lotus's ability by tapping it, adding at least three mana of any color.
3. Activate Trazyn by paying 2, untapping it.
4. Repeat from step 2.

This clever combination transforms Trazyn the Infinite into an infinite mana engine by turning graveyard utilities into active powerhouses. With Amoeboid Changeling granting Trazyn all creature types—including Sliver—Scuttling Sliver bestows its untap ability upon Trazyn from the graveyard. Meanwhile, Trazyn's Prismatic Gallery ability absorbs Nyx Lotus's tap ability directly from the graveyard, letting you tap Trazyn for a massive influx of colored mana based on your devotion. By simply spending a portion of that generated mana to untap Trazyn via the Scuttling Sliver ability, you can repeat the process infinitely to flood your mana pool.
