Aeve, Progenitor Ooze + Temur Sabertooth + Mana Echoes + Chromatic Orrery

Aeve, Progenitor Ooze

Temur Sabertooth

Mana Echoes

Chromatic Orrery

How it works

1. Activate Chromatic Orrery's first ability by tapping it, adding 5.
2. Cast Aeve by paying 5.
3. Aeve's storm ability triggers, creating a token copy of Aeve for each spell you've cast before it this turn.
4. Resolve the first Aeve spell.
5. Aeve enters the battlefield, triggering Mana Echoes, adding C for each Ooze you control.
6. Repeat from step 4 for each Aeve spell remaining.
7. Activate Temur Sabertooth by paying 2, returning the nontoken Aeve from the battlefield to your hand.
8. Repeat from step 2.

This ingenious engine turns a single cast of Aeve, Progenitor Ooze into an escalating storm of oozes that fuels itself endlessly. As each copy and original Ooze hits the battlefield, Mana Echoes triggers to flood your pool with colorless mana, which Chromatic Orrery then helps filter and expand into the colored mana you need. With your mana flowing, Temur Sabertooth can bounce the original nontoken Aeve back to your hand, allowing you to recast it for an even larger storm count and keep the infinite loop spinning.
