I’m curious to see how well it does too, I submitted it because I thought it was cool not because I thought it was good and I don’t have the patience to gauntlet anything
Wouldn't the Arbor deck lose to Draco? As long as Leyline of the Guildpact is still on the battlefield with it, Draco has hexproof, so Binding can only target the Leyline itself. And because of Dryad Arbor's summoning sickness, there's no window to cast Binding before Draco resolves, even when on the play.
