I don't know what to have for the rest of my sideboard because I have only been playing Bo1 arena. my LGS didn't have any fading hope and it will take a month to get anything online any ideas for what I can replace it with?
Reckless Impulse is better because you can cast it at your convenience. You plan a volley, then Impulse. With Rob, you need to cast it, then plan. Things can go wrong.
Rona's Vortex is the closest equivalent to Fading Hope. It's a downgrade, so maybe split it with Shore Up. I like Ancestral Anger, but you do need another use for those islands, and with Levitating Statue, you're geared to a longer game that Shore Up makes possible.
