Mulligans
Very strong control deck. With Darkportal you can play big taunt from turn 5, or drake to clear board turn 4 if you lucky. Deck have enough early game removal to survive aggro until reach there.
On the other hand, Control matchup should be easy. Beside all your minions are sticky , big combo turn with betrug+ plot twist, the killer move is ebonlocke+sath combo turn 10. You will have 4 prime and fill the board with big minion 4 times more….thats a pretty win condition
Thoughts on adding Warlock Quest to this deck?
Yeah just cut 1 big minion. But does the quest really matter? The deck win by huge swing turn ( if you dark gate betrug you can do the plottwist combo from turn 5) or play Prime fews times in slow matchup.
