So I've been trying to word an emblem for a custom planeswalker so it gives the first card played each turn Flash, but so multiple emblems stack, giving each subsequent spell flash. I've been trying to find a precedent in MTG and have only found the following (maybe):
Make copies of Erayo, Soratomi Ascendent and flip them, either with Mirror Gallery on the board or using Helm of the Host, so they become Erayo's Essence which reads "Counter the first spell played by each opponent each turn". If I have, say, 4 of these effects does it counter the first spell four times or the first four spells?
I'm trying to keep the text on the card concise and easy to understand, but if I weren't I would have it read:
You get an emblem with "The first X spells you cast each turn are cast as if they had flash, where X equals the number of emblems you have with this effect. Only one emblem effect counts toward the total number of spells you may cast each turn with Flash gained from these emblem effects." This leaves little to interpretation, but has a ton more text than can fit under a planeswalker's ability.
Any help is appreciated.
