Fatigue Questline Warlock

Hang on to Backfire to the end.

Frontload Flame Imp and Hecklefang Hyena.

Opponent will try to kill them early, so handy to use raise dead as soon as you get one or two of them in graveyard.

As soon as you have both Backfires in hand, use Soul Rend and Altar of Fire to get rid of cards.
