So... using the stat topic values, Lyon deals .89 PCHP MT magic damage (might be more with the harsher skill loadouts?) and Wren deals .58 physical MT damage (might be less if you use a non-existent 3-turn damage average?). That's just gonna sweep some teams on the spot.
Flip side, dunno how people vote XG gear bosses, but I am inclined to harshly disrespect their speed after turn 1 due to the existence of the mighty Boost. Yeah yeah other games have broken buffs too that cost even less than XG's fuel drain, but since XG 100% guarantees every character will have it, I'm more inclined to punish bosses for its existence.
Team Black vs. Team Bald - Shakhan survives the initial burst, is not soloing.
Team Black vs. Team Pink
I think Rika *must* try to ID Lyon, as things go to crap if she does something else. On the bright side if it hits, even though Wren doesn't care about TP busting, Team Black is defanged enough that healing + Nel status carries. If Rika misses her ID - which is more possible vs. the speedy Lyon - then Team Pink explodes for sure. Anyway per Random, Rika got the vote over Tir, so.
Team Black vs. Team Green
If Demi uses Recover, the rest of her team gets swept, Mario & Cyan put pressure on, and Lyon kills her before she can use Medic Power to revive everyone. So... she uses Medic Power for .26 PCHP MT healing. This means that Lyon/Wren's burst dealt ~1.20 PCHP total to everyone. Demi & Gale are dead, but FE10 Neph might have barely survived, and maaaaaaybe Clive? Anyway, doesn't help, Neph Wrath's somebody out then gets slain by Cyan's ITE Dispatch or something.
EDIT: Oh right Demi has mech-only ID. And then Gale gets a turn and Neph mops up survivors. OUCH. Nice catch, DragonKnight.
EDIT EDIT: Per Jo'ou, Demi gets OHKO'd anyway. Oops.
Team Black vs. Team Teal - Blitz'd.
Team Black vs. Team Red - Kaboom.
Team Black vs. Team Purple
Lyon Twilight Runes everyone (killing Miang), Liza blows up Wren, Lyon smashes the poor-MDef Lyon (with magic triangle advantage, even, not that it's needed), Mario jumps on... Liete, probably, Enclose is bad times. Hmm.. Liza has 1.08 PCHP, took .89 from the Twilight Rune, can Cyan deal .19 PCHP with a regular physical attack?! According to the stat topic, no! FAIL. Cyan CAN finish off Liza - if his rando-targeted Dispatch hits her rather than Lyon. That said it might not matter if Cyan can finish off either? Liza might not OHKO Mario through Ghost Medal and Lyon certainly doesn't, so think Team Black baaaaaaarely steals this one thanks to MARIO and CYAN.
Team Bald vs. Team Orange
Lenny's petrify the only threat here, so Team Orange focuses him down, except their damage is actually rather bad. I think they need Rhys damage in there to do it on turn 1, and Rhys / Basilio threat range split isn't clear... neither are good. So on second thought, Wakka Triple Fouls Basilio, and then Alena will get Petrified. Wakka / Citrine damage is bad though... matters a lot if Alena got a crit when she was hitting Lenny to see if they can finish Lenny off round 2 before he Petrifies Wakka. Oh but wait, Wakka has Stoneward. Okay, yeah, that's it for Team Bald, Shakhan & Rude fail forever vs. Wakka who out-drains their magical offense even if they take down Rhys.
Team Bald vs. Team Silver
Micaiah & Hope both have status-healing for Lenny... although I guess Basilio can just smash Micaiah's face while Lenny tries to Petrify Hope? Hope will stack some stone resistance, though, and Akihiko's offense debuffing, if it goes before Basilio, can save Micaiah. Although maybe not, Rude can chip in some awful damage too. So... Hope can stall a bit then revive the fallen Micaiah, Lenny can try and Stone Hope... hrmm, Team Silver actually has some serious problems getting in offense here, Setzer/Pamela damage is not gonna kill Lenny all that fast. And Shakhan will start emitting some awful MT fire damage eventually as harassment which will tie up Pamela's turns on draining. Maybe Akihiko's turn 2 Masakunda next gets in some crucial evasion? But Team Silver can't wait forever before both Micaiah & Hope end up stoned / dead and then it's all downhill. Hope needs to stay Medic, he can't afford to switch to Synergist and throw up Veil I don't think. Open to arguments.
EDIT: Eh, leaning Team Bald, forgot that Hope can't get Petrify resistance. Silver's offense is just too bad to kill Lenny quickly.
Team Bald vs. Team Brown
Lilka is target #1. She fears both petrification and Basilio + Rude just smashing her. Still, she can double-zap Basilio with magic (and eat a Bow counter). Basilio kills Lilka, Rude does something. Anastasia finishes off Basilio's awful RES with some of her magic. Lenny petrifies Guv. Labby revives Lilka. Hmm - I forget how initiative worked in XF with revival, but if revived Lilka can get a turn in fast to de-stone Guv, they basically win on the spot. If she doesn't.... not sure it matters, Basilio is dead, Anastasia is still loose, and Labby's revival restores 85% HP so lol at Rude working that down.
Team Bald vs. Team Blue - Lenny gets *smashed*, the rest of the team follows.
Team Bald vs. Team Blond
I guess if you see Marle as not blocking SH2 petrify this *might* be close but since petrify is rather blockable in SH2 itself I'm inclined to let it work for her.
EDIT: Or Basilio could just smash Marle's face in and revive-lock Kornell while Lenny stones the rest of the team. That works too.
Team Black: 4-2
Team Bald: 2-4
Basilio's killer robots look like they've been foiled.
