If you're trying to find a replacement for intuition, just don't do it. Gifts Ungiven is just not a good card in madness, and I can't think of any thing else that would replace intuition. This is the deck I used to win an extended tournament recently. It wasn't a very high level tournament, but the deck still worked really well, even without using Intuition.
I've been trying out a RGu splice deck. I'm suprised there aren't any other topics on splice decks here. but anyways, here's my decklist. suggestions and improvements are welcome.

I've found UB spiritcraft to be very good. It wins with thief of hope, flyers, and devouring greed. I've found blue to be better than green just because of ribbons of the Reikei
usually the only time I get angel abunas is against affinity because it's almost always gg. I'm still trying to decide whether I should run angel/abunas or vamp/trike though.
