Psychosis Crawler + Scrawling Crawler + Windfall + Teferi's Ageless Insight

Psychosis Crawler

Scrawling Crawler

Windfall

Teferi's Ageless Insight

How it works

1. Cast Windfall by paying 2, causing each player to discard their hand and each opponent to draw cards equal to the greatest number of cards discarded this way, and you to draw twice that number due to Teferi's Ageless Insight.
2. Psychosis Crawler triggers for each card you draw, and Scrawling Crawler triggers for each card opponents draw.
3. Resolve the Psychosis Crawler triggers, causing each opponent to lose 1 life for each card you drew.
4. Resolve the Scrawling Crawler triggers, causing each opponent to lose 1 life for each card they drew.

This lethal concoction scales catastrophically by supercharging your card-draw engine; when you cast Windfall, Scrawling Crawler and Psychosis Crawler watch every card fly into your hand, while Teferi's Ageless Insight doubles your intake. As your hand explodes in size, Psychosis Crawler's power swells to match it, transforming your massive card draw into a barrage of life loss. Meanwhile, Scrawling Crawler ensures that even the simple act of your opponents drawing cards from Windfall bites them back directly, sealing their doom.
