Ramos, Dragon Engine + Agatha's Soul Cauldron + Eldrazi Displacer + Voracious Brood

Ramos, Dragon Engine

Agatha's Soul Cauldron

Eldrazi Displacer

Voracious Brood

How it works

1. Activate Eldrazi Displacer by paying 2C, blinking Voracious Brood. Voracious Brood enters with at least five +1/+1 counters due to its replacement effect.
2. Activate Voracious Brood using Ramos's ability by removing five +1/+1 counters from it, adding .
3. Repeat.

This clever loop transforms Ramos, Dragon Engine into a ten-mana powerhouse by utilizing Agatha's Soul Cauldron to grant Ramos's counter-conversion ability directly to Voracious Brood. Once Agatha's Soul Cauldron has exiled Ramos into the graveyard, the resulting creature gains the power to strip five +1/+1 counters for a massive influx of colored mana. Eldrazi Displacer then steps in to reset Voracious Brood, whose own replacement effect immediately restocks those crucial counters upon re-entry, leaving you with an infinite cascade of enters-the-battlefield triggers and boundless colored mana.
