There's two possible archetypes you could go from here: the denial-rush, and the stall.
The former consists of 3 or 4 Discords in a 30 card deck, supported by Abominations and Purple Dragons, with 1 or 2 Maxwell's Demons thrown in for good measure. The latter is a bigger deck (35-40 card range) that aims for a control win via Discord and Purple Dragons with Diss Shield, Pandemonium, and Antimatter.
The rush works nicely on AI3, and can do OK in Bronze League (though the prevalent Immorushes and mono-Aether will give it some problems).
