ABR / Amaranth / chuva de perereca / Gefährlicher Random / Heroic Troller / Nails / Serpi / Sceptross - Players who are clear RBY OU starters. The first seven should be pretty self-explanatory, while Sceptross is an old Pokemon Perfect boomer who is the only player who's competed in every RBY Invitational so far and has yet to finish in the bottom half (Top 12, 3rd, Top 16, 4th). He has been grinding with chuva de perereca all year and his level is on pair with anyone in this list.
Khaetis / SaDiSTiCNarwhal - Players who should round out the pool as starters or support to pair with those who might want to swap. Khaetis won RBY Invitational III without dropping a single set, including wins over marcoasd and Kaz twice. He sat out this year but has time to deliver in SPL XV. He's has great game sense, especially in the long term, and Kaz and spies directly vouch for him. SaDiSTiCNarwhal finished Top 8 in RBY Invitational IV with wins over Kaz and Lusch, has the second best record in RBYPL/RBYWC all time (behind only Serpi), 2x RBY Individual Winner, and has prior SPL experience. Get this man back in the spotlight.
Excal / Laroxyl / Kenix / TDK - Players who can easily start in RBY, but will likely be needed in other tiers (DPP / SV / GSC / SV / TBD)
chub / Ctown6 / nicole7735 / Sabelette - Players who are likely on the cusp of playing in SPL / would likely get a chance to start or support this year if the pool wasn't the most stacked since SPL IX.
Want to double down on the Narwhal recommendation. He is 100% an SPL player. Narwhal carried our Retro Cup team with the best record, I think 6-0 or 5-1, and we had teammates like Lax, Star, Marcop, Finchinator. Narwhal is really really good and has proven he can win in team tour environments.
