I know that this is for PvP, but I had a few quick goes with this vs 5 FGs, won 2 vs Obliterator, 1 vs scorpio, 1 vs Osiris and lost 1 but forget which FG.
I'll test it properly later and report anything else. Actually surprised how well it works
Edit: Had another few tries with it, this time with much worse results: only 3 out of 10 FGs were wins, though a lot of the losses were VERY close.
Edit 2: I also thought about adding 1 explosion to counter sundial decks, since I'm not too bothered with having exactly 30 cards. Also, I get 5-6 ttw, not 2-3, though maybe that's my bad draws
