If it wasn't for the fact that one Dim Shield is usually enough to net you a loss x)
At least if your opponent has at least HB-class offence.
Good for Balls though. Back when SoP was an 'Other' card, I'd 6-turn Elders with Fractal Balls. Fastest MA ever.
However, since this deck already packs so many buffs, SoP is somewhat inefficient. It would be good if you only draw Balls, as you said, but mostly because that lets you attack with them until you draw Cremation+better offence. The risk is that they'll get CC'd since they only have 1 HP. Without Cremation fodder you're in trouble.
