Every day I'm shufflin'

Step 1. Turn your opponent's cards into frogs / pigs / random units / silenced units.
Step 2. Shuffle them back into their deck as dead draws.
Step 3. Shuffle your deck back in so you can do it again too.

Probably horrible.

Other ideas:
Justice for more wraths / silence effects.
Fire for Unexpected Results and other firebomb shenanigans.
Primal market, for things like Mind Link, Rain of Frogs, and Lightning Storm
