Aggro Shaman KaC

if you get the perfect mulligan (with Jade Claws), Southsea Deckhand is the best entry, but Fire Fly can help in a first turn.
Scorp-o-matic is a good card to keep, because, if you play something like: Southsea Deckhand + Patches, Coin and Fire Fly, and the oponnent play a doomsayer, you have a good remotion.
Jade Claws is a good card to help in removes, and active Charge from Southsea.

Bloodsail Corsair is a good start versus aggro, because he pull a patches and is a better trader than Soutshea Deckhand, like, he is not dead by any HeroPower, and survivor a minion with 1 Attack.
Scorp-o-matic can kill some cards like, Patches, Bloodsail Corsair, Fire Fly, and the Righteous Protector, and majority of early games.
Maelstrom Portal is a good remove in area.

Scorp-o-matic versus control can beat doomsayer, righteous protector, northshire cleric and some early games.
If you start with The Coin, you can keep Flamewreathed Faceless, because its a big pressure on turn 3 (ofc he can get removed by a polymorph, or a shadow word, hex, but in general its a good pressure)
