Breya, Etherium Shaper + Animation Module + Sunbond + Crystalline Crawler + Kaya, Geist Hunter

Breya, Etherium Shaper

Animation Module

Sunbond

Crystalline Crawler

Kaya, Geist Hunter

How it works

1. Activate Kaya's second loyalty ability by removing two loyalty counters from it, causing you to double any tokens you create this turn.
2. Activate Breya by paying 2 and sacrificing two other artifacts, causing you to gain 5 life.
3. Sunbond triggers, putting five +1/+1 counters on Crystalline Crawler.
4. Animation Module triggers, holding priority, activate Crystalline Crawler's first ability three times by removing three +1/+1 counters from it, adding 3.
5. Resolve the Animation Module trigger, causing you to pay 1 to create two 1/1 Servo artifact creature tokens.
6. Repeat from step 2.

This intricate loop transforms Breya, Etherium Shaper’s artifact-sacrificing lifegain ability into a self-sustaining engine by channeling it through Sunbond, which cascades that life into a massive influx of +1/+1 counters for Crystalline Crawler. Those counters can then be stripped away for mana to fuel Animation Module's token creation—with Kaya, Geist Hunter doubling your token output to ensure you always have enough fodder to feed Breya again.
