This is a fun deck exploiting the synergy between Summoning Portal and Glinda Crowskin.

First of all, you have to somehow survive until you have gained 10 mana crystals and hold Glinda Crowskin and Summoning Portal or Meat Wagon in hand. Use Kobold Librarian to draw, upgrade your spellstone and remove your opponents opening minion. Get out Plated Beetle, Tar Creeper and Vulgar Homunculus to stabilize. Hellfire them and just stall as long as possible.

Once we have gained 10 mana crystals, try to get out Summoning Portal and Glinda Crowskin. The ideal play would be to summon the portal via Meat Wagon without having to pay for it the turn it gets out. Then, the fun begins... spam the board with 1 cost echo Lifedrinkers (for 15 damage / heal if you have only glinda and portal on your side!), Omega Defenders or Gnomeferatus. If you face a full enemy board and somehow don't have to fear lethal, you can even go for 5 Sea Giants.

I added Baleful Banker, Zola the Gorgon and Faceless Manipulator for consistency. If you fear insta-removal, you can copy Glinda and the portal and maybe pull the combo off twice.

Enjoy!
