Hmm, I didn't think Snivy can get its HA+friend ball combo because I *think* only males can pass the ball when breeding with a Ditto? :/
Moon/Love Balls are my favorites too :3 I plan to use my Love Ball on a HA Eevee for Pixilate Sylveon and Magic Bounce Espeon. That might be hard though... thank goodness we don't have to wait for a female to appear, lol. As for my moon ball, I want to save it for a HA Rowlet if and when that becomes available so I can MM a shiny Decidueye in a moon ball.
If it just never becomes available (or comes as an event or something), I might use it on Mimikyu.
I did catch and breed a couple Friend Bounsweets and I just caught a Heavy Magnemite if you're willing to trade one for a Heavy Honedge
and if you want both, I'd like a Moon Litwick when you get it. Would that be a fair trade though? I've never used Island Scan and don't know how much work you have to go through to get pokemon from it.
