These are just my predictions. I made them based off of the designs and their possible typing, move sets, and stat spreads.
Robingroot: Sniper
It fits its archer theme nicely, and it would go well with STAB moves like Leaf Blade and Sky Attack.
Panthster: Tough Claws
Being a heavy-hitting wrestler with razor-sharp claws, I can see it having this ability. It would boost some nice STAB moves like Fire Punch and Crunch.
Entermaid: Serene Grace
The ability matches its elegant design. It works really well with STAB moves like Scald and Moonblast.
