By the way, regarding the Disheft. I didn't think the Guardian Satan had much of a chance, but in the end, the opponent got frustrated, barely made it through a bunch of wards to my creature, lost two or three Dishefts in the process, and then I continued to defend until he simply ran out of options and conceded.
By the way, I'm not even sure what to upgrade. On the one hand, I could use more healers – it would be good to add Lucifer and Isri. On the other hand, I need to improve Themis and the Tribunal, as I only have one copy of each. Thirdly, any decent control deck now counters the Bahamut, and since I have more than one Guardian Satan in my deck, destroying amulets isn't my biggest problem. However, against a player with two Polyphonies, who beat me in round 167 with a very long battle, the Bahamut would have been very useful.
And yes, I recommend adding the Dark Jannah to this deck. It triggers a ward and has a good AoE attack.
Oh, and one more thing. In this game, the Scyton came into my hand before the Grail, but I discarded the Grail earlier because of its AoE effect; I don't really want to leave units on the board if I can avoid it. The evolved Scyton would have cleared one, but the opponent had two.
