A few observations...
Dark Confidant keeps the good stuff coming, and is in my opinion worth a light splash. I'd probably replace Quirion Dryad with him.
Mishra's Bauble seems an auto-include. Bigger Goyfs, Opt effect with fetch lands. Lotus Petals are also an option. Baubles make either Grim Lavamancer or Nimble Mongoose decent. I'd consider Lotus Petal if I ran Confidant, probably not otherwise.
My current version is
4 Kird Ape
4 Mogg Fanatic
2 Grim Lavamancer*
4 Tarmogoyf
4 Dark Confidant
4 Lightning Bolt
4 Seal of Fire
4 Chain Lightning
4 Fireblast
4 Lotus Petal
4 Mishra's Bauble
2 Urza's Bauble*
4 Wooded Foothills
4 Taiga
4 Bayou
3 Bloodstained Mire
1 Mountain
*questionable slots
- Just 1 basic mountain. With only 4 spells of each, Lotus petals are enough to get around annoying Wastelands/Extirpates. All red spells apart from 'Blast cost 1.
- Flipping Fireblasts over is rarely a problem. Having it tends to put my opponent far enough in the red zone that they have more important things to do than applying pressure themselves.
- Nimble Mongoose is possible in the place of 'Mancer. It's either stellar or terrible; I prefer the more dependable Lavamancer. If you run Mongoose, Fireblast is an excellent tool for reaching Thresh.
- If nothing else, goose is a reason not to run 3-mana stuff. It's a 'late game' beater that allows you to cast the rest of your hand on turn 3-4.
