Fairy type was introduced in Pokemon to balance dragon type and make poison a bit more competitive, as Pokemmo is a competitive Pokemon game with up-to-date move-sets why not release Fairy type, this would mean change the typing of the few existing pokemons that are now Fairy ( examples: Ralts, togepi...), and with this release the Fairy moves that are not in the move-sets of these pokemons making them much weaker. (ex: Draining Kiss).
I also suggest the introduction of the evolutions of the pokemons that got an evolution in later gen (examples: Togetic to Togekiss, Magneton to Magnezone).
Finally i want to ask if u are ever going to use gen 7 move-sets, because Zubbat now learns Absorb instead of Leech Life ( Leech Life is now a 80 base power move Physical learned at later stages) and that would really hurt Squirtle starters.
