Sharmista vs Nightburn: Much faster, 2HKOs.
Sharmista vs Massimo: See Snow.
Sharmista vs Oswin: Surprised Sharmista turned out this bad.
Sharmista vs Rikku: Guessing that Sharmista's stun is turn 3.
Nightburn vs Massimo: I think. Gets the drop in with a shot of gravity, and huge speed advantage from there should seal it.
Nightburn vs Oswin: Double Graviton, then double Dual Impulse. Double Graviton reduces him to 1/4 PCHP, then double Dual Impulse kills average, so only the likes of Mog might survive that. Os can get a Javelin and two Silver Lances in, though, which probably kills. So... Nightburn has to retreat to Crush (doubt 3x Javelin kills). Oswin has just under 3x average pdur, 75% average pdur after double Graviton. Crush... is not killing... except if it's elementalised. Do I allow elemental Crush? Nightburn goes first and has various elemental hexes beside him, even if this is a random map instead of his own, so... yes, yes I do. Good enough. Close match though.
Nightburn vs Rikku: Nightburn probably puts too much pressure on ABP, and Rikku can't win with an overdrive (Nightburn can't be statused, and the lag after an OD just murders her even if she buffs).
Massimo vs Oswin: Think he's too tanky, and counters don't help (although Massimo can Power Charge instead of attacking... still don't think it's enough).
Massimo vs Rikku: Busts healers.
Oswin vs Rikku: Killer Axe.
Nightburn 4-0
