Help

I restarted moon and decided this run that I would use alola raichu half way through.

I've stumbled into the problem though that I can't catch pichu because all of my current pokemon are too high leveled to bring down the HP and I can't even catch it in a great ball, which is currently all I have at this point in the game.

Could someone be so kind to trade me a pikachu or something? Here's my friend code for the kind souls who could exchange it:

Thanks in advance
