Spell DH is really fun
All the top decks feel really on rails. Bubble pally, aggro druid, dragon warrior, herald shaman... They all feel like you're just slapping minions down trying to race for the turn 6 or 7 kill.
Spell DH feels different. I feel like there are actual meaningful decisions with your cards. You can trap yourself with bad Outcast card placement. You can sacrifice tempo by saving your Fel spells for Nespirah and still come out on top. Turn 6, you can opt to play The Eternal Hold to high roll a game-saving demon, or just play other cards for a more reliable response. If you misplay, you could potentially lose out on a couple Argus portal triggers.
It feels really good to play. If you're looking for something not boring, I'd recommend putting a few games into Spell DH and really try to figure it out.
