Scuttling Sliver + Trazyn the Infinite + Amoeboid Changeling + Five Hundred Year Diary

Scuttling Sliver

Trazyn the Infinite

Amoeboid Changeling

Five Hundred Year Diary

How it works

1. Activate Amoeboid Changeling by tapping it, causing Trazyn to become a Sliver until end of turn.
2. Activate Trazyn using Five Hundred Year Diary's ability by tapping it, adding at least .
3. Activate Trazyn by paying 2, untapping it.
4. Repeat from step 2.

This clever little engine comes together by bridging graveyard utility with tribal identity, letting Trazyn the Infinite borrow activated abilities from the artifacts resting in your graveyard thanks to its Prismatic Gallery. To make Trazyn eligible for Scuttling Sliver's untap ability, Amoeboid Changeling steps in with its tap ability to ensure Trazyn temporarily becomes a Sliver. With those pieces in place, Trazyn can freely tap to leverage Five Hundred Year Diary for a massive influx of blue mana, scaled by your Clues. You then pay the {2} untap cost granted by Scuttling Sliver's ability to ready Trazyn once more, looping the process to generate infinite blue mana.
