"I feel pretty"
Cloud, Lucius (FE7), Caina (WA2) vs. Kyogre, Clive (WA3), Ephraim: *looks something up* Water Spout is MT. Oh man, 1.23 PCHP damage off 119% speed if he goes first. Which he does here. Cloud gets OHKOed, Eph finishes Caina, Lucius ain't soloing.
Cloud, Lucius (FE7), Caina (WA2) vs. Anastasia (WA2), Lawfer, Drachma: Yeah, Impulse hurts, Lawfer hurts. Ana is actually below average speed, but outspeeds Caina, so she'll get a turn for sure.
Cloud, Lucius (FE7), Caina (WA2) vs. Lady, Killer: lolno
Cloud, Lucius (FE7), Caina (WA2) vs. Tibarn, Marle, Kyle (S5), Algus: Sadly, Team Pretty just isn't very good.
Team DARKNESS
Cthulhu (CStW), Athos (FE7), Sierra (S2) vs. Kyogre, Clive (WA3), Ephraim: Cthulhu is the fastest here, and he needs to make Water Spout less insane. So he Dark Strikes Kyogre for 43% of its HP. Kyogre uses Hydro Pump instead to bump off Sierra, who is very dangerous. Eph and Athos... both want to wait for the other to go first, but Athos has to or Clive+Eph will act together and kill him. Gut says they can bring him down one way or another, even if he kills one of them in the process, and Kyogre + the other should be able to deal with Cthulhu.
Cthulhu (CStW), Athos (FE7), Sierra (S2) vs. Anastasia (WA2), Lawfer, Drachma: Nothing stops Sierra from getting a turn and vaporising somone. Hell, the entire team is faster, here (unless Lawfer goes before Athos), so it's possible that, say, Sierra MT + Cthulhu and Athos ST picks off two people before they move.
Cthulhu (CStW), Athos (FE7), Sierra (S2) vs. Lady, Killer: Again, superior speed carries the day here. All three attacking Lady should kill her, and Killer goes after everyone. But... only Sierra has good MT, so only one of them can die. Lady death counter goes off. Killer must kill Cthulhu lest Cthulhu go again, and only a ST attack is good enough. Next turn he... can't possibly kill both. He can go for silence but that's dicy against Athos res, and anyway physicals from Sierra are legit. So he kills... let's say Sierra. Can Killer survive one Sierra spell + one Athos spell? Yeah, both hit hard, probably not. Good fight!
Cthulhu (CStW), Athos (FE7), Sierra (S2) vs. Tibarn, Marle, Kyle (S5), Algus: Sierra outspeeds Tibarn and a Finger of Death on him is really bad news. Yeah yeah Marle can revive if she even gets a turn (Cthulhu + Athos can ensure she doesn't). Kyle/Algus aren't coming back from this.
Bringers of Light:
Raze (MK2), Kurando (SH2), Serge (CC) vs. Kyogre, Clive (WA3), Ephraim: Kyogre is clearly faster than Kurando, actually! MT doom happens.
Raze (MK2), Kurando (SH2), Serge (CC) vs. Anastasia (WA2), Lawfer, Drachma: Yeah, lightbringers getting the speed drop here should ensure they win the slugfest.
Raze (MK2), Kurando (SH2), Serge (CC) vs. Lady, Killer: My Lady HP respect isn't so low that Kurando+Raze can kill her. If Serge also outspeeds Lady the fight gets better, but I think they're still in a lot of trouble, as the Malice Dirge counter stings and then Killer can spam MT to finish this (since the team lacks anyone as magically tanky as Athos).
Raze (MK2), Kurando (SH2), Serge (CC) vs. Tibarn, Marle, Kyle (S5), Algus: Tide's analysis seems mostly on for turn 1, but turn 2 not so much? In order for Kyle to actually die, Serge needs to use a tech, which means he isn't outspeeding Tibarn turn 2. Tibarn's going to OHKO Serge, and then Raze has nothing ITE.
