Reminder text ought to be fairly doable. Create a mechanic with text something like "_( may be paid with either \1 or one mana from a \2 permanent)_", and then invoke it with "[ElementalReminder {W} Air]".
Though a 5/5 Flying creature that sends your whole team to the skies whilst grounding your opponents - potentially as early as Turn 4 - is pretty nifty.

Not sure if this is splashy enough or balanced but it does show how Affinity would work in the set.
