I own a copy of every single Minotaur printed, but I keep struggling with coming up with a decent tribal deck.
It appears that Wizards is now trying to push Minotaurs into R/B. Think they will keep up the trend? That said, I wanted to try making either a R/B or R/B/W Minotaur deck.
White doesn't really add much to Minotaurs exception Boros Reckoner and the utility that comes with White. I fear that if I add White, the deck just won't be as aggressive as I envision fanatic bovines to be.
Right now I am strongly leaning towards R/B in the hopes Wizards will throw us cow lovers a bone with a decent legendary Minotaur in R/B in Theros block.
You should try out five colour tribal. Minotaurs are in all 5 colours, so you get to play all of the sweet one's. I've been testing with Horde of Notions, featuring a minor Elemental theme for support. It has been a lot of fun, actually. You also get to play the 3 Mazes for flavour reasons.
