Early Rift or Soul cards are what you're looking for to start.
Seeds of Destruction
With the multiple Fel spells added to Warlock’s arsenal it’s only clear to implement it to Duels; what better way than with the soul package!
This deck combines the soul synergy with the newest fel treasure “Imp-credible Trousers” which shuffles 2 Fel Rifts into your deck after casting a Fel spell. The goal is to constantly have your board filled with 3/2 Flame Imps and 3/3 Fel Imps.
