West Wind Pack

Currently my favorite 'for fun' deck. I'm terrible at piloting this deck and I could still get a roughly 50% win rate.

With the recent Feastcaller buff I'm trying to incorporate him in here as well but haven't had enough Shiftstones to spare.

Unstable Form + Permafrost are your primary single target "removals".
Lightning/Hailstorm to fend off go wide aggro.
Yeti Furflinger turns anything into a Storm-able creature.

As with any combo decks, you need to dig your pieces...and in this particular deck I prefer "loot" mechanic (draw 1 discard 1) because you also need ways to put things in the void for West wind Herald.
The crests are there to help you find answers / combo pieces too.

So the combo is pretty simple, you cast Mirror Image / Strength of the Pack on your Herald and they just start multiplying.

There are times where you shouldn't fixate on the combo and just start mirror imaging Yeti and Torgov and beat up things.

Eilyn is just there for stupid fun but most of the time she never comes out, gets discarded, or board wipes your Heralds with a random Lightning Storm.

Have fun!
