I want to run a sashed Vivillon for doubles, but I'm unsure about which ability to use. Compound Eyes would help with this such as Sleep Powder and Hurricane, while Friend Guard would reduce damage taken by allies. Please help me decide which ability is best and explain your reasoning :D thanks
Eh, it depends on your vivillon. A defensive vivillon or supportive one would get more out of friend guard, but a more offensive (lol, wouldn't use "sweeping vivillon") would get more from compound eyes.
