Ok so i finished breeding the remaining mons (skarmory, passimian, porygon & purrloin). My entire HA mon inventory has been processed now, but there were a couple that I processed without putting them into special balls.
The below 8 are the only ones from my entire HA mon list that are currently not in special balls, followed by my preferences for what ball I'd like them in.
-Goomy - Dream or Love Ball
-Lapras - Lure Ball
-Natu - Dream Ball
-Skorupi - Dunno honestly. Maybe Dream Ball? or Level Ball? Edit: Actually Safari Ball might be best. But any of these 3 will do.
-Skrelp - Dream or Love or Level Ball.
-Snover - Friend Ball I guess.
-Swablu - Love Ball
-Wailmer - Lure Ball (or possibly heavy ball, wailord is a heavy mon after all =p, but lure ball would be preffered)
Additionally, if you manage to find a Sport Ball Eevee I'd definitely love to have that too. I'd then have HA eevee in any special ball =D (except beast, but I dislike the look of that one and have been keeping it out of my mon inventory)
My current HA Natu hurts the most (still in a pokeball T^T), the others are in ok balls (for example my HA wailmer is in a Dive Ball), but not special ones.
