It's almost fully maxed ditto, is it useful for anything?
It's very situational. A ditto copies the Pokemon's stats but not the moves, so if you put it against one that doesn't know moves that are super effective against itself but has the potential to (i.e. Gengar) then it can beat the opposition if it's a higher level.
If it's a higher level than the opponent, it might be better, depending on whether it rolls better or worse moves.
Also, it keeps its own hitpoints, so it will also be better against glass cannons (i.e. Gengar, Alakazam etc.) than tanks (Blissey, Snorlax etc.).
You really need to know what you're doing with a Ditto, otherwise it will be shit
It can be good if you know how to utilise it properly.
Two pleasing egg hatches today; a very good quality Rhynose from a 5k and an Aerodactyl from a 10k. Neither particularly necessary but with time the Rhynose will be good for evolving,
Rhydon has an evolution in Gen IV, Rhyperior, so you definitely want to save candies for it as it will be a beast.
