Celes, Rune Knight + Crystalline Crawler + Gravecrawler + Phantom Train

Celes, Rune Knight

Crystalline Crawler

Gravecrawler

Phantom Train

How it works

1. Cast Gravecrawler from your graveyard by paying .
2. When Gravecrawler enters the battlefield, Celes's second ability triggers, putting a +1/+1 counter on each creature you control.
3. Activate Phantom Train by sacrificing Gravecrawler.
4. Activate Crystalline Crawler's first ability by removing a +1/+1 counter from it, adding .
5. Repeat.

This loop transforms the recursive resilience of Gravecrawler into a powerful engine, fueled by repeatedly casting it from your graveyard as long as you control a Zombie. Phantom Train acts as the sacrifice outlet that feeds Gravecrawler back to the graveyard while temporarily animating itself into a creature, while Crystalline Crawler provides the mana neutrality by converting its own counters into the black mana needed to recast the crawler. Meanwhile, Celes, Rune Knight watches these graveyard entries trigger its ability, pumping your entire board with infinite +1/+1 counters to overwhelm your opponents.
