EDH/Commander General

Play them, it worked for my playgroup.

tutor up a commanders beacon

Maybe you could try Olivia Mobilized for War? Rakdos has a bunch of no blocking allowed cards and Olivia is a way to give Phage haste from the command zone

Play with anothee group as well

But Daretti and Sram are both good artifact commanders that give you value. So why not put them both in a deck headed by a General that cares about artifacts being on the board?

why is boros so shit
whites fun on its own
reds fun on its own
but there are 30 boros commanders that all do the same shitty thing

They can and probably should go into the deck, sure. But you're not going to have access to them every game from the command zone, so why not build around Jor Kadeen instead?

just because the commander says "play doods, turn sideways" doesn't mean you have to do exactly that. You could use the commander as a finisher while building up a board state of taxation effects and hate bears, or use the various artifact synergies in both colors to gain incremental value throughout the game.

1) Red and White are supporting colors. When you just have one color the difference between supporting and the colors that can do their own thing is rather small. Green isn't that much better than Red. When you combine the two colors that have trouble standing on their own though, they don't get much better, while every other combination does. Gruul or Azorius just have so many more options than Boros.
2) Wizards is bad at trying new themes. Boros is the Boros Legion, so they're all about combat, everything is fighting, all the time. Can't be anything not related to combat.

I didn't say I was building around them specifically. What I meant was to take the elements of both decks that work well together and put them in a deck that is lead by a general that also synergizes well with them.
