16. Sweepage vs. 9. Mounts - On paper, Sweepage should have the edge on DPP/BW. I think Mounts can create an upset if he prepares well. Sweepage is great but his flaw is that he's easily counterteamable, as he always plays the same kind of teams, and that's something that can be lethal in a playoff environnement. Also, Mounts' aggro playstyle can be tough to deal with when playing something too fat. But the result will mostly come down to how well Mounts prepared (minus lucky breaks xd)
2. cosine180 vs. 10. PokèManiac Livio - Just bring some Stallbreakers and you're good
14. blunder vs. 11. SoulWind - Highlight of the round, both are very good players. While SW has more experience in old gens, blunder showed last round that he's not slouch either. I'd predict blunder to take ORAS, the final result will come down on whether he'll be able to snatch a win in BW or DPP, where SW has the advantage given he doesnt bring something too stallish.
13. Malekith vs. 5. Ciele - Cool matchup. Malekith is the remaining player with the biggest skill variance, but if he's on a good period (and if he doesnt bring his doubtful gimmicks like scarf snorlax), he's really tough to beat, as we saw during his BW match vs PDC. Ciele is very good too, but since Male seems on a good form i'd give him the edge.
