I'd take out the miracles, swap some pends for pillars, and perhaps add some deflag.
The Miracles have won the game for me more than once with this deck. I think the Pendula are important in order to get Hope out early, and the only time I've found Explosion could have helped was against Dimensional Shields which, in AI3, is rarely encountered anyway.
Maybe even remove the hope, since this looks like a fast rush deck.
But without Hope the AI will target your Seraphs on their first round and kill them instantly which, again, happens more than you'd think it would.
Besides, you take out Hope, then there's no point in having the RoLs, and I'd have to try to find another card that starts with a K or which sounds vaguely like "que" to build a deck around. "Plague Seraph Seraph", perhaps. "Quake Seraph Seraph"? "Flay Seraph Seraph"? "Drain Seraph Seraph"? "Phase Seraph Seraph"? If you're going to make a pun-based deck, then it makes sense to at least keep one of the cards used for the pun as one of the elements you're going to be using anyway.
I suppose there's always Deflagra(tion) Seraph Seraph, but I don't think even I could use a pun that bad without feeling a little bit cheap for it.
