Ive been toying with this list for a few weeks and twerking it. Recently saw this one made a fair result on MTGO http://tcdecks.net/deck.php?id=25050&iddeck=196608. I think the deck has some potential but needs more tuning.
The interaction between gideons (when transformed into creatures) with karakas is worth mentioning, since you can use it either to protect it (from STP or any edict effect) or for using it twice each turn (attack, bounce, cast again and use another ability).
