Note: I have absolutely no insider source so its all gonna be speculation and guesswork but anyways here we go
==============
AMERICAS
==============
First off the South American teams are highly unlikely so thats half the teams gone, leaving us with SEN, C9, EG, 100T, NRG and G2. Its probably not SEN cause their teams pretty much fixed already and its probably not EG considering they're broke rn.
Leaving us with C9, 100T, NRG and G2. Now the whole reason the leaker community is giggling away and refusing to give the community any news is cause its "gonna give everyone a surprise" So either the move will be REALLY hype or it would be something no one would ever expect. It's probably not 100T considering they're going budget team (I think?) If we're going by hype then yay to NRG will be the most logical. If we're going by unexpectedness then...well all 3 of the remaining teams are sorta expected, but I reckon C9 would be the most likely considering the "role issues" are solved and also itd be pretty funny but then again C9 is also going budget. It could also be G2 but that would be way too underwhelming honestly.
In conclusion, for AMERICAS, the 2 most likely teams are NRG and C9, personally if I had to chose it would be NRG. However given all the "hype" around yay's move I would be surprised if he actually joined an NA team cause that wouldn't really warrant the "Haha you'll never guess where he's going" reactions of the reporters
==============
EMEA
==============
Same as before we get rid off non-english speaking teams first so FUT, BBL and Gentle Mates are gone. FNC is also unlikely since their roster is pretty much confirmed. I don't really know much about the current situations surrounding the teams in EMEA so I can't really analyse that deeply but if I had to choose from the remaining teams I would say its either TL or KC. Team Liquid cause looking at Flynn's spreadsheet they're still missing a duelist on their team. It could be KC cause that would be a VERY unexpected move and would definitely warrant a "No one would've guessed" reaction.
In conclusion, from the EMEA side I think its gonna be TL or KC
==============
PACIFIC
==============
Pacific is a tough one cause theres like no info on half the teams but I reckon it isnt gonna be ZETA, DFM, GENG and DRX UNLESS they decide to build a roster outside of only JP/KR. I dont think its TALON but the only way I ever see yay goin there is cause him and b0i were on andbox???? yeah it just seems unlikely. It could be T1 considering Sayaplayer hasn't been re-signed yet but that would just be a weird move if you think about it. Probs not PRX as well since Something is alr a top level duelist and their core is pretty strong so i dont see them getting replaced this year. It could honestly be TS cause it seems like everyone's forgot abt them and they're missing a duelist but I highly doubt yay would go there. In all honesty its probs between GE and BLEED. But if I had to guess itd be GE but BLEED apparently does have the 💰🤑💰soooooooooo
========================
TLDR for those who cant read allat: GE, KC, BLEED, NRG, C9
Honestly id put my money on GE and KC. KC especially cause I would understand why "itd be funny seeing everyone's reactions" from the leaker's POV
