After messing with this theorycraft a little, I've come up with some pretty interesting things.

1. Elise the Enlightened can develop loops with Flobbidinous Floop. When you play Elise, you get a copy of Floop in your hand, letting you then loop Floops until you can amass a hand of several burn spells/life gain/removal/etc.

2. You can also initiate the loop above with either Zola the Gorgon + Youthful Brewmaster, or two Zolas and an Innervate.

3. Elise also lets you obviously copy Malygos, which is why Twig of the World Tree is pretty crucial here. The better part is, Elise can let you get one or more copies of Twig, letting you get insane amounts of mana in one turn, especially combined with Emperor Thaurissan and Innervates.

4. This isn't really a discovery or anything, but Archmage Vargoth and Keeper Stalladris can give you huge advantages and burn. With Thaurissan Living Roots/Wrath, and Innervates, Stalladris can provide a ton of burst in his own right, and Vargoth just plays really well with Ferocious Howl, Wild Growth/Jade Blossom, Branching Paths, Nourish, and Swipe. I really wanted to test him with a Oaken Summons package first, but I felt like it'd be less consistent than this version would.

5. There's several combos of cards here that offer an OTK, which is great for an OTK deck. I'm not going to list them all and I'm sure I would miss some, but most involve Malygos, Flobbidinous Floop, Faceless Manipulator, Twig of the World Tree, Emperor Thaurissan, Innervate, etc. That's probably not news to many, but I'm glad that the limit of singleton doesn't really hinder the number of ways to put together an OTK that much.

I think the cards I'd most want to squeeze in currently are Azure Drake and Bloodmage Thalnos, but I'd rather wait to get Elise to mess around with before changing this much more.
