If you convince your playgroup to allow it, Coalition Victory is a great win-con in any five color deck.

I totally love this idea about "breaking the color pie"! It's very creative. I think this deck could use some work in terms of relying more on and using the commander. O-Kagachi is a really good card and can work as a commander better with cards like Day of Judgment or other board wipes. Then you can keep them from building back up their creature army with O-Kagichi. In addition, you may want cards that can give your commander unblockable, like Aether Tunnel , to make sure you can get the best of it's ability and always deal your opponent damage each turn. You should also add some pump cards so that once O-Kagichi is unblockable or nearly unblockable (either from spells or hopefully because they have no creatures left) you can attack for enough commander damage to win in only a couple turns.

Good luck!

The_Epic_Dog: I have heard of that card before but totally forgot about it. Would make a great addition for a win condition.

nospamspam722: To be completely honest, I just picked one of the 5 color Commanders that sounded kinda cool and didn't really plan on building around him. I could very easily make this deck a sorta Voltron Control deck while still keeping the breaking the color pie theme. I'm going to look further into adding some cards to buff O-Kagachi. I'm thinking it'll probably have to be auras, but not sure if there are any that would work within the theme.

Just checking that you know Coalition Victory is banned and that's why you'd have to convince your playgroup.

Nope, didn't know it was banned. Might be able to convince them to run it since we're not really playing by the rules for these decks anyways. For example, we're allowing the silver bordered legendary creatures as Commanders even though the silver bordered cards are banned.
