I like the idea of connecting the two events. I would considering using it in the other cards as well since it makes the cards much more exciting for other formats.

I think I will do that on more cards. It certainly solves some issues regarding e. g. the power level discrepancy between Planar Exile and similar in different formats and it would work nice on spells named after planeswalkers.

I'll have to decide on a case-by-case basis though e. g. Planar Bond clearly doesn't want it.
