Predictions? Black will be based on Hymn to Tourach or Fatal Push; Red will be a better Pyrotecnics (although I'd love a free Light up the Stage) and white will be a token generator.
There is no way black is getting an instant speed, pitchable Hymn that is legal in modern. They already have unmask and it is probably right where the power level needs to be. More likely they get creature removal because it's black, and I would assume white gets an instant speed pitch protection spell.
