I did do as you said and added Drain Soul instead of Plated Beetle, I find that to be better aswell 🙂

I gotta say, this is my favorite deck right now, having alot of fun with it.
Tho I’ve made some changes,
I removed 1 Power Word: Shield for 1 Holy Fire, I felt like I never ever used 2 PW:S and with Skulking Geist i most often ended up removing 1 or 2, so I saw someone run with Holy Fire, so I tried that and found it to be better.
I also removed 1 Scale Worm for 1 Twilight Acolyte, it’s just so nice to have against aggro (Mountain Giant).
Those are the small changes I did, but to me it feels better that way 🙂
