Firebat can be seen playing the list in this video: https://www.youtube.com/watch?v=0dxspK6uS-Y
Plays similarly to oldschool miracle decks, with a burst finisher from Leeroy but also from Deckhand + Cold Bloods + Faceless. With Valeera the Hollow, you can get 3 Cold Bloods, which is pretty neat.
The Ashmore package helps thin your deck to get to the combo. Vicious Scalehide is also pretty alright vs aggro, especially combined with Cold Blood for more healing. Sherazin is mainly here to distract your opponent and eat up their time/resources so you have time to draw into the combo.
You could also consider replacing Deckhands with Boars, since you only lose 2 burst and don’t have to worry about having the weapon up.
what could i change for sherazin? for now i feel vilespine is really necesary for evenwarlock and gain a lot of tempo on other matchups
If you cut Sherazin you’d probably want to get rid of the whole Ashmore package, so the replacements would be double Vilespine and double Minstrel to tutor.
