I'd actually recommend dropping the Ally theme as it's not supported strong enough within the deck. And add moreeee Oath of Nissa. Having run a 5-color Hippie deck before, I know from experience that Nissa's Oath is KEY. Plus, each one you set down cycles through your deck for more Walkers. Devote your creatures to mana ramp, control, and survivability rather than actually having them be a subtheme. Reflector Mage, Fairgrounds Warden (or even Isolation Zone), Kalitas, Traitor of Ghet, Gisela, the Broken Blade, Gearhulks (specifically Noxious Gearhulk, Combustible Gearhulk, and possibly even Cataclysmic Gearhulk if not only in the sideboard).

More control. Superfriends is a SLOW build, unfortunately, and it requires patience on your part, but even moreso on their part. You're going to want counters and killspells and board wipes, to the point of frustration. I encourage Manlands as well, since you won't have adequate room for creatures.

I've never played a SuperFriends deck, but if I was, I think the following is how I'd go about it...

Mainly with a copy or two of the other basic land colors needed.

Full playset of Evolving Wilds Dig for the land I need when needed, depending on my hand.

Full playset of Oath of Nissa. You'll just need it.

Jaddi Offshoots and Primal Druids and generally anything else below 2 CMC on the green side that will give me mana choices or gain life until it's time for the WEEKEND (a.k.a. when 'friends' come out).

Keeps the mana a little less chaotic. Hoping to pull the right land at the right time barely works in 3 color decks... going for all 5 is lofty. Not impossible, but I've been land screwed in 2 colors...

What do you think?

I honestly think your creatures are bogging you down. If you're going to play Superfriends, commit to it and play at least 20 walkers with additional oaths and deploy the gatewatch.

Get ready for the next Ajani ;3
