There was one Lum who got absurdly lucky with items and beat me in the Lum mirror once, maybe that was you. If that was the game I’m thinking off he had several rounds of throwing 2-3 Fireworks in a handful of item tosses. I think I’ve only ever lost the Lum mirror once besides that.
I was also thinking you might be a Rook player, but I’ve taken at least one match off pretty much every Rook I’ve played so it’s possible I may have never played your Rook. If your were playing Jaina / Grave, then yeah, obviously you’ll win because those matches are free.
I’ve played against Squible a lot and while he definitely plays well, I don’t really feel like I see a lot of unique style, he just plays the matchups better than other players and makes fewer mistakes. That being said, I have taken him to game 7 with Lum as virtually every character he plays.
Actually, the fact that games go to 7 is, IMO, one of the worst things about this game. It just makes bad matchups so much more unplayable. The way you generally win bad matchups is to gain momentum and then overwhelm the opponent, but the fact that every round resets the momentum makes victory extremely unlikely. Over a large number of rounds, the better character will generally win out. This is why you see characters like Rook and Lum having such polarized matchup spreads. I’m honestly not sure what the logic behind having characters have very little health and having a lot of rounds was, it feels like it was borrowed from Divekick but it served a very different purpose in that game.
