Have to go with the others: this deck is going in too many directions to be viable for very long. Go with the angel theme and stick with the white Planeswalker if you want to keep him, but ditch the rest and round out the mana pool to white sources. Look for some white/red painlands or dual lands if you insist on keeping both Akromas.

Recommended: adding all of the named cards to your deck. Most people like to be able to click on the links and view the cards instead of typing them in.
Eesh. No love for black in this deck, no sir. Talk about a headache.
Hah! Very nice. Even original, in a weird sort of way. Looks like fun. If you can give them untargetability or Fear or some such effect, that'd be a neat trick, too.
Assuming that the Wild Growths are doubled by mistake (in both Enchantments and Land sections), and with 26 forests, you're a total of 72 cards, which is approximately 12 too many. Go down to 20 or 22 forests; you've got no mana issues to work with this deck. Nix the cards that don't fit your deck theme like Spore Frog and Fog -- you're all about dealing damage, not preventing it. Also cut out unnecessary mana fixers (Overgrowth, Nature's Lore). Trim down the singletons and get to 60 cards.

I'm getting back into Magic about about a 2-3 year hiatus (or longer; Ravnica was hitting the scene when I stopped playing), so a lot of the new cards are still unknown to me. That might be a good addition -- what to replace, though?
