Combo is Dizo's Racket
+ Kesava, Trueheart
+ Amaran Camel
+ Xenan Fanatic
First play Racket, then Righteous Intent
(Draws you 3 cards and gets your Kesava at the expense of 3 net damage).
Then put Kesava on the board, then the Camel. Next time you gain life or draw a card, this will draw your entire deck, gaining one life per card that you've drawn. Finally, play Xenan Fanatic and have it do 60ish damage directly to face.
I doubt this is the best configuration of this deck since I'm a noob, but here's the rest of my card choices:
lets you put Camel or an appropriate merchant on the board to pull what you need.
and Display of Vision
ramp you, get you influence, and stall for time and occasionally pop face aegis.
does standard market/aegis popping stuff. Backlash protects your combo pieces and pops face aegis.
buys you time, and occasionally is a really expensive face aegis pop.
is in the optional 5th spot, could really be whatever you want. Just seems right to have an emergency sweeper, though like most combo decks aggro is a bad matchup. Malediction
is a good choice too. Could also toss a relic recovery card in here.
BE CAREFUL WHEN TIMING THE COMBO! Pulling Fanatic from market counts as a draw, so make sure you have 4 power left to cast it, otherwise you'll deck yourself instead of winning.
