25 is good yeah I'd assume, I'm 30s, because I basically when I catch a new Poke I train it to match the older Pokes before I start normal battle (odd/old/boring habit), either by grass or daycare of both.
ALSO Eviolite is an AWESOME item for Scraggy waiting for it to evolve, I'm making it hold it, more bulk is certainly welcome with natural bulk, Moxie AND Work Up to raise attack (current "set" is Payback Brick Break Hi Jump Kick Work Up).
