Decks

To explain the abnormal picks...

Perfect Grade is very powerful against mono-Blue decks. His two armor is invaluable against a color that lacks hard removal, and his -2 kills the majority of their creatures. If the meta moves away from Blue, PG is a weaker pick.

The Serpent package (Empress, Scourge, Den) is great against aggro and control alike. I think it's well positioned.

The Decoys allow us to cheat out Tangleskein, Twin, Transport, and Perfect Grade. They also allow Misanthropia + an enchantment/creature on turn 5-6.

Mind Freak is tech against Angel Loop. We can't beat a looping Angel, so we need to take away the option.

Reincarnation is fantastic with Sapo, Twin, Tangle, Transport, and Jin. It gives us resistance against sweepers.

Red Cliffs helps us avoid Sidecar shenanigans. If you can stick something strong on Cliffs vs RO, you've gone a long way towards winning.

Bob is a great engine, and does an average of ~3.8 damage. You're pretty safe going for a highroll.

I like Mutant over Yahui, but I could be wrong.
