I really like the idea of Law + Disease (was the main reason I liked the deck in the OP) but I don't know what to pair with them.
I like the combo because Law has a lot of good counters to units and Disease can deal with scary heroes. It gives it some effective counters to different stuff. I like Blue in general but outside of Free Speech I don't get how to effectively use Quince and his spec.
The next deck I want to try is [Law],Peace,Disease. Law for strong unit counters, the hilarious fun of Community Service, and Blue lock down. Disease to fight heroes by killing them, discarding spells (which subs in for a semi Free Speech), give Blue a 3/3 for 2 (what madness), and another generally solid tech II choice. Disease also gives a strong tech I recipient of insurance runes (Plague Spitter). Peace gives the deck an offense hero (something really lacking in the OP deck), the very valuable 2/2 for 0 in multi-color, and all the other stuff Peace does.
The main downside to the deck is token units are at an extreme minimum. It has the dream combo of making the opponent discard 5 cards though. That would be pretty sweet.
Is there a third spec that would be better/more interesting to combine with Law and Disease?
