>>40109298Rabbit or Chameleon is gonna be the shillmon, probably Rabbit, with Sobble being the cutesy mon they push alongside.
Grookey probably will end up the third wheel.
Combatwise...
Grookey is gonna have a hard time beng good. Big gorilla doesn't really scream fast, and a bad secondary type(or a lack of one) could spell instant doom. If we assume the demo was at least somewhat true to how their stats will end up, it just gets worse, as Grookey seemed to mostly just be balanced across the board with SpA being the only notable low stat(but with no high stat).
Scorbunny is really likely to end up Fire/Fighting, which is a really good typing. It's likely to be very fast and fairly frail, so the specific Speed, Atk and Sp.Atk are gonna play a key role. If the demo is representative, it will have stupidly high physical attack, high speed, and garbage everything else.
Sobble seems to essentially be the Special equivalent to Scorbunny based on the demo- stupid Sp.Atk, high speed, garbage everything else. Probably gonna be good because Water-type is a benefit, not a weakness. Second typing is gonna be really big if the demo stats are representative, since it would really help a fast attacker to have a second STAB.
