As we await Standard rotation and a modern banning, this is not a generally exciting time for decklists. Luckily, there are still some heroes out there, like QMUNKE, who took this insane and/or brilliant concoction to a 5-0 record in a recent Modern League:
Modern Esper Rally
It’s impossible to know if this is an optimized list for this strategy, but there are a lot of sweet thing going on here. I truly enjoy playing two copies of Jace, Vryn’s Prodigy to supplement Magus of the Bizaar, and I’m always happy to see an Ideas Unbound.
The strategy here is to interact with your opponents creatures with Sidisi’s Faithful and chump blocking, much like the Standard Rally the Ancestors deck, and then to kill your opponent with Blood Artist/Zulaport Cutthroat triggers. There’s also an outside shot that you can win with Bloodthrone Vampire in combat, though mostly you’ll just be using it to sacrifice creatures so Rally doesn’t exile them.
I really like the inclusion of Bloodghast and Bridge from Below as the go-to cards to discard, especially considering that the onus is going to be on your opponent to kill their own creatures if they want to remove Bridges. You can also just build a huge army of zombies with any of your sacrifice outlets if you win the Bridge lottery with Hedron Crab and/or your discard outlets.
I don’t actually know how good this deck is, but it’s definitely worth paying attention to, as there are a number of cards in this list that would be poised to spike if this deck takes off. Specifically, Magus of the Bazaar is worth less than a dollar, and being from Planar Chao makes it old enough to increase in price substantially if it suddenly becomes relevant.
