I think @deku means is that the attack animation, it attacks you twice when fighting them, wasting 1 second of your precious time?
Can't think of reasons why this is useful, but yea. XD
Aso, don't they have like, 25% more attack because they attack twice? (second attack being 50% of the first one)
I have MLB Devi & Lady Devi and they are currently my strongest Dark type. I like how fast they charge as well.
