I got a cursed espeon at lv1465 and had two trainers bring it to that lv but now its extremly hard to lv it up

Use trainer richard

try useing the attackes bolt strike, blizzard, v-create, and closecombat, and faceing swimmer in npc fights.

Fill your team up, all using v-create and fight in the grass tower. Best way I can advise to lvl up after 1k

Best way is to first get a team of golurks/goletts and teach one of them Toxic for 4,500 coins from the Department store. Then face mystery trainer, use toxic on the Mew, use the golurks/goletts to lower the hp of the mew and make sure the pokemon you want to level up get the final attack

@markinatorz, that's what I do, depending on what your highest level is, it gives you extreme amounts of exp. 1 mew for me can bring a base level to level 400 something. I highly recommend this if you can afford toxic

well there are also a way in which you cost some coins go to market trades section and find a cheap trainer who trains pokemon i recomend emonovember he can train it to level 10k but not free
