I've always been a big fan of Null Profusion. Lately I've been trying to think up ways to make it work in Modern. I tried burn, didn't work as expected (though I didn't think of Braid of Fire). In Type 1 it and its green ancestor have been used alongside Fastbond to great effect. So why not start there?
The combo here is Early Harvest and lands. Lots of them. Explore and Summer Bloom, with Profusion out, are positively insane. And Crucible makes it so that even if you run into a string of dead draws, you still don't run out of gas - just play a fetch from your graveyard (you still draw from Profusion, lolwut?!) Eventually you reach critical mass and cast Early Harvest, untapping all your lands and hardcasting Flying Spaghetti Monster.
i played around with a version before the bannings that used red rituals like rite of flame and manamorphose to essentially play a bunch of free cantrips, then win with grapeshot. definitely gets weaker after the bannings, but it still can win turn 3-4
