I'm really on the fence about Gate to Hell.
If you're going with a Pentagram strategy, that +1 Melee is a lot..
You could take down a swarm Beastmaster's whole team with the 12 mana 2nd ability.
And it's unquestionably super cool.
I just don't know if it's any good. Compare it to Tooth & Nail. Gate costs 12 mana, instead of 7, and 1 Melee isn't that much better than 1 Piercing. Yes, opening the Gate can be pretty effective, but it's probably going to light your Warlock on fire too, and the cost is huge! And 6 points to put in your spellbook? Yikes. Tooth & Nail is much more affordable at 2 points.
Maybe the Gate will get better when there's a lvl 2 Demon to summon.
Or maybe it's good right now and I would know already if I was playing the Warlock a bunch.
Thoughts?
