MO still got that devotion frost deathwish list going for them. It's not top tier and got almost no removal but no NG meta deck can keep up with those points even after developing the Ball twice.
BTW were I to digress, ppl always complain about NG toxicity but overlook that MO can push even harder in the direction of cancerous, tilting game play. Look at the clog list (
https://www.playgwent.com/en/decks/f2af0143005a9c31bbc24358f2f1e453 spams Haunt and Dethlaff, Golyat in R1 just to force a pass, making like 55 points in 3 turns, and then cheaply clogs enemy rows within 4-5 turns in R3 with 3-4 Noonwraiths from Caranthir and Operator followed by Ritual Sacrifice and Meanhorn/consumes, finishes with Jotuun and Glusty). If given R1 this is pretty much unbeatable and makes you discard 5-6 cards from long R3. No NG deck can go that far in disruptive toxicity. Or Keltullis. They say NG destroys a unit every turn. Well, it doesn't. But Keltullis really does.
The only difference was that those MO lists are rather meme, and Double Ball used to even be Tier 2 once upon a time. Well, now, they're all meme.
