Drawlock

You draw cards. So I’m not the best deck builder but with some of the cards given and especially some of the portal demon cards I can see a “draw warlock” come into fruition. I’ve never really built any kind of deck, and I’m pretty new to the game (this is my first year rotation) so please tell me if I’m lacking in something important. The main goal of this deck would be to draw your Portal Demons and Fel-lord Betrug to create rush demons to keep board state.

Things like Phantom Militia, Voidwalker, Hellfire and Doomsayer are there to hold the line in the early turns, not to mention Phantom Militia is one of the few good taunts out there since other taunts are rotating out and Phantom Militia goes well into the late game. 

Soularium is in the deck to draw through your deck to activate portals and Betrug, as well as plot twist to search through you deck in a pinch since your try to keep a large hand. 

Rafaam is also in the deck just for longer control games. If you shuffle multiple portals into your deck you are able to get additional legionaries. If a deck like odd-warrior pops up again where the main goal is to outlive your opponent Rafaam will be there for a power-swing and a fatigue bonus.  

The Augmented Elekk is there for the same reason, it combos with Plot Twist and both your Portal Demons and adds cards for Rafaam.

Godfrey and Hellfire deal with big boards, siphon soul for single targets. 

Then some more taunts like Rotten Applebaum, Zilliax, amd Aramaso Broodmother not only act as taunts but restore health. 

This is all theory crafting right now and I want to try and experiment with deck idea more later on as the meta evolves and I get better at deckbuilding but for now I’m happy with what I’ve made.
