Okay, this is a random idea that came to my mind while considering the magic systems of the Nasuverse and of the Magic: the Gathering multiverse. I concluded that yes, there IS a way to make the two coexist and still keep their own brand of magic.
Simply put, the Nasuverse is a 'lost shard' that was born at the same time as the Shard of Twelve Worlds in which Dominaria, Ulgrotha and the other "origin" planes in MtG are located.
The cataclysm that shattered the multiverse and created the Shard had a notable effect - namely, it caused magic in the Shard to develop differently than magic in the rest of the Multiverse, because the Shard became physically and astrally isolated from the rest of the multiverse.
To use a geology analogue, it's like what happened when the supercontinent Pangaea broke during ancient times - and life began evolving separatedly on the pieces, giving way to today's diversity.
Well, this is what happened to the Nasuverse in this idea - like the Shard of Twelve Worlds, it broke off the 'main' multiversal mass and became isolated.
However, UNLIKE the Shard, the Nasuverse was truly isolated - while the Shard was pushed a ways away, it was still close enough to Shandalar, the extreme corner of the main multiverse, to one day make it possible to planeswalk there again, and it happened, during the Ice Age.
Not so with the Nasuverse - it was flung so far away during the cataclysm that all contact was lost, because the distance is so great the Blind Eternities filling the space between planes will kill a Planeswalker long before they can safely reach it. As such, magic and mana in it developed very differently from Magic's. The source of power is still the same, technically (a rose by any other name and all that), but the laws and nuances governing it and its use are very different due to different evolution.
That... was the situation until recently. But, thanks to the Mending during the Time Spiral arc, all realities grew close together again - and that includes the long-lost Nasuverse. Close enough, in fact, that a determined Planeswalker or two can reach it now... and discover a new world where magic works very differently from the way they are used to.
This is the basic groundwork of the idea. With that said, Planeswalkers would find it very difficult to use their magic in the Nasuverse - the mana doesn't work like they are used to in it, so for the most part they will have to bring along their own mana-producing artifacts to make up for this difficulty (Moxen of all denominators, powerstones, colored Diamonds, Ramos's body parts, Totems - they all will work, it just means Walkers will be far less powerful than if they had full access to the plane's mana).
The clash between Magic: the Gathering wizardry and Nasuverse mystical arts should be... interesting, to say the least. In a way, the Nasuverse developed its own Planeswalkers - that's what Reality Marbles, and to a lesser extent Noble Phantasms, are essentially mimicking. On the other hand, summoning magic is far less advanced, due to them being so remote they didn't have access to other Planes' creatures for summoning, something a Planeswalker will be able to do with great ease compared to typical Nasuverse summoning.
This is just a rough idea and could use some improvements. It's aimed at balancing things out - Magic is, at its core, on a much higher level of power than Nasuverse magic, so introducing a story reason to at least initially nerf it is basically a requirement. Also, both sides have things they are better at than the other.
Suggestions?
