I'm teambuilding right now and I'm stuck between two choices for my Garchomp. Should I slap a Choice Scarf on him, or is a Mega Garchomp the better choice? I'm working on an offensive team. Basically it's Speed vs Power. Or should I use Choice Band or Life Orb instead? The other Pokemon I have on the team are:
Greninja, Azumarill, Espeon, Aegislash, and Darmanitan.
