Long planeswalkersona lore
Been watching some MtG lore videos and I was struck at how transference of the planeswalker spark was a viable thing.
Pondering creating a villainous group for Ikko to oppose. One based on the twisted idea of the meritocracy: a group of 'walkers who take sparks and give them (read: sell them) to those whom they deem "worthy".

So naturally they'd consider the idea of a lowly goblin possessing a spark as a waste of a precious resource. One that would be better off in someone worthy like the multiplanar fantasy equivalent of Elon Musk.
