Chain of Smog and Witherbloom Apprentice is the combo.



Chain of Smog can be copied any number of times when you target yourself. Magecraft triggers for each time you copy the Chain of Smog.

Vulnerable to removal. Both pieces cost 2 means Spell Snare is good.

Here's a super-rough SI shell of it. Summoner's Pact can be a mana source or a win condition seems quite strong.

4 Witherbloom Apprentice
4 Chain of Smog

4 Ad Nauseam
4 Wishclaw Talsiman

4 Summoner's Pact
4 Elvish Spirit Guide

4 Hope of Ghirapur

4 Dark Ritual
4 Culling the Weak

4 Lotus Petal
4 Chrome Mox
4 Mox Opal
4 Lion's Eye Diamond

1 Dryad Arbor
3 Bayou
4 Verdant Catacombs




Entomb and EoE is another route, which leads to reanimation lines for Witherbloom Apprentice. Diabolic Intent could be good with Summoner's Pact.
