To be honest, you might has well have stopped at 8.
Well, there's really no great reason to have any more than 6.
However, I like to have more than I need so that I don't have to worry about making sure I take them off every Pokemon before I put them in the PC. It's a luxury, but that's how I roll. --- LA LA LA LA LA LOVE ME LOVE ME LOVE ME LIKE IT'S PROM NIGHT | 3DS FC: 3437 - 4335 - 3104 | | Friend Safari: Panpour, Wartortle, Frogadier |
