The other seven three color pairs are easy for me
Mardu is war
Naya is big monsters
Jeskai is USA
Jund is the food chain
Grixis is Bad guys
Temur is grow fast
Esper is sneak and connive
But the other three have no imagery/association to me. I’d be curious if anyone has an association for them similar to what I’ve listed here.
I had a Bant Goodstuff standard deck back in SOI, so I think of it as cathars, elves and countermagic.
The person who got me into Magic had a Prophet of Kruphix commander deck (before the ban) so I think of that creature as Sultai.
I associate Abzan with Ajani for some reason (though he is more Naya himself), not sure why. Was that his home?
