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.
BUG is actually a really helpful association! Thats Sultai down at least.
