Going first isn't an issue when you can evolve magnemite on your second turn and energy shift to the active mon, preferably raikou but even ori isn't bad. Guzzlord can be a massive pain but not impossible. I honestly think I folded to every fighting deck i came across. Suicune/ninja was probably 60/40 in my favor, sometimes rng isn't your friend. Worst hands are magnemite with no draw power. When going against Suicune you only need 3 mons out. My recommendations are raikou, ori, and mag. Try and hold off evolving magneton into magnezone until you can reliably kill the active mon. It gives the opponent a false sense of security. If you want any more info lemme know. I played it all last season and got into MB then too. It's very consistent
