Tough question as all the colors have characteristics of multiple types.
INTP is a hard one to peg (P seems rampant only in red and partially blue (really only in cards like show and tell, tutors, omniscience, minds desire) Id guess izzet or temur, maybe simic.
Azorious is definitely the guardian (ESTJ) I believe.
Rakdos (ISFJ?)
Gruul (ESFJ)
Dimir (INTJ)
Esper (ENTJ)
Those are my best guesses.
Personally, I enjoy playing Dimir, mono black/blue, sultai, temur, and Gruul the most. Green is my favorite color, but I never play it alone. Just some creatures I like a lot (Omnath, Locus of Mana, skinshifter, primetime, scavenging ooze)
I despise the white gameplan as a whole. Really limits my options in EDH because I refuse to play white, but there are some great white cards I want to use some day especially in Naya or Bant.
Do you play on MTGO at all?
