I believe it was Pentad Prism -> Horde of Notions. It's a pretty functional (and sometimes explosive) deck though, all the creatures are Elemantals and there are some really nice synergies between some of the cards (e.g. evoke with Parallax Wave in play).
I think I'm at, like, 98% completion. I've got a 540 with the color proportions I want. Cut most of the sketchy cards, there are still a few to test, but I think my testing time will be spent on balancing now. If anyone has time, let me know.

So, when I was playing ramp, I really wanted a high-end card that could deal with multiple opposing threats at once. I feel like Dragonlord Atarka is a good incentive card, but maybe too bomby?
In general I feel the Converge mechanic was much better executed than Sunburst. I have had my eye on Engineered Explosives, but some of the others feel both less interesting and less powerful than converge alternatives. Infused Arrows is the most appealing to me, but is also at a rather...
Bloom Tender I'll find a slot for (suggested cut?). Which Sunburst cards do you want?
Myr Superion is supposed to be sketchy. But I've pulled it off in paper and it felt amazing. Pod into it? Chord into it?
