[ChaseInfinity]

So I'm currently breeding a team and I'm down to my final Pokemon Raichu, and I forgot pichu Was a baby Pokemon so I went to see how you evolve it and I saw its one of the Pokemon that evolving with Max happiness, so I was wondering is there another way (besides genning but it might come to that) or do I just have to suffer through every time I wanna put Ina me pichu with better ivs I have to max his happiness and evolve it?
