I win, simulator says 43% chance for me to win.Simulator AI only seems to be able to "properly" play Siphonary (and the losing decks xD), every other deck I won with supposedly has a disadvantage despite the fact I won. And even then, tracking a simulation showed me it fails to use Sundial in every possible way (it just insta plays it and ignores it's drawing potential) and fails with Siphon Life (insta plays on opponents' health).
(43+85+83+20+34+60+61.9)/7=55.27% average chance per game for me to win.
Good thing there's more than just the decks played that affects outcome
