I think the second deck is weaker, since SoV is so slow, but either of decks 1 or 3 look alright to me.
Deck 1: Probably better for gold/plat. Less permanent reliance (SoVs are gonna get blown away by SoF) and more healing I think gives this one an edge.
Deck 2: I wouldn't use this one. Probably does best against slow healing stalls with no PC. (ex: FGs fire queen or ferox)
Deck 3: Probably better for silver. My reasoning is that there's a lot of monoaether in silver, and a wise morning glory blows right past dimshields, and the fact that it's probably a bit slower than #1 will not matter as much against silver where the decks are weaker and generally have less hp.
It would take some major redesigning, but your third deck made me think of making a deck kind of like that, but with mirror shields and quints. You'd have the option of flying glories or quinting opponent's creatures and SoWing them. Has anyone ever done that deck?
