The name of the game here is cheating huge monsters into the game early and steamrolling from there.

Using Fenvale Muse + Rivers to fix mana problems/Set up a good Shapeshift result.

Mulligan aggressively for 3 lands and if possible always keep a big monster in your hand (always keep Doom or a Hydra) minons with evasion are so important your biggest threat is early spot removal.

Lots of fun combos here!

Frogs on the avatar "Kiss of Judas" can draw you a lot of cards (even though the 'attack' doesn't do any damage still counts as an attack.

Monstermorphosis on a frog or cheap minion

Shapeshift sort of risky (Use your opt engine with River's/Fenvale Muse) but will often hit a good minion.

Maiden, Mother, Crone with Shapeshift often makes it firmly in enemy territory however it's so useful to not stall out later game so try to consider it when shapeshifting.

Cuts/Considerations

Will probably cut 1x Swap and 1x The Rack, while its cool to potentially hit em with a bunch of frogs its just too easily countered.

Big hater of Ring of Morrigan did not add it to my list.

Omphalos were cut due to not often not very useful due to drawing sites which they can't do anything with.
