Joking part of me just says "Gather," but the serious part of me says something around the five colors, like 5 Lands, or something much more creative revolving around that.
Lots of joke answers I want to make here but "Planechase" feels like it could've been the name if the game came out in the 00s or 10s instead of the 90s
"Planeswalker" would be catchy in an alt universe. It feels like cheating to say "Sorcery" but "Sorcery" would also work but is basically just a synonym.

'Eternities' if it had to be something new.
Duelwalkers
(But this is true either way)
Or Arcanum
