Golgari Thug + Aluren + Weatherlight Compleated + Phyrexian Altar

Golgari Thug

Aluren

Weatherlight Compleated

Phyrexian Altar

How it works

1. Activate Phyrexian Altar by sacrificing Golgari Thug, adding one mana of any color.
2. When Golgari Thug dies, it and Weatherlight Compleated trigger.
3. Resolve the Golgari Thug trigger, putting it on top of your library from your graveyard.
4. Resolve the Weatherlight Compleated trigger, putting a phyresis counter on it and causing you to draw Golgari Thug from the top of your library.
5. Cast Golgari Thug by paying 0 due to Aluren.
6. Repeat.

This clever loop relies on Aluren to cast Golgari Thug completely for free at instant speed, while Phyrexian Altar provides a way to turn that creature into any color of mana upon sacrifice. Whenever Golgari Thug hits the graveyard, its own death trigger puts it right back on top of your library. This seamlessly feeds Weatherlight Compleated, whose passive counter accumulation triggers every time a creature dies, allowing you to immediately draw the very card you just stacked.
