sorry color me confused. is MTG and forgotten realms the same thing? why are they appeared as MTG cards?
Separate IPs. There is crossover in the medium used though. For example, MTG is planning Lord of the Rings and Warhammer 40k cards in the future-it doesn't mean that space marines and Gandalf could team up with Jace the Mind Sculptor. Similarly, Pathfnder publishing adventures in the 5e ruleset doesn't mean that Pathfinder is in the same 'universe' as Darksun.
