I've definitely had more moments this season where I seemed to go through rough patches, but got on a good run this afternoon and got to Infinite. Seeing more varied decks now though, and things are definitely more challenging.
I got Wong as my free series 3 card, so have been playing more On Reveal with him. Still sticking mainly to HE, and then my Sera and Patriot decks, both with Iron Lad. I had one Conquest matchup earlier with Sinister Labs where Iron Lad copied Sera on turn 4 and duplicated, then I played Sera and she duplicated. So all of my cards on turn 6 were -4 cost. Everything cost 1 except Doom, who cost 2. So played Shang, Absorbing Man copied him, then Doom and something else to fill out the rest of the board, whilst I wiped out three or four of his cards. Good times.
