Commander Strategies without a Commander
I've, on more than one occasion, have wanted to build a commander deck and had to settle for a less than perfect commander, since there isn't one. For instance, I have a Abzan life gain matters deck (because green and white are the best at gaining life but black and white are best at taking advantage of it). I played for years with Daghatar, the Adamant as my commander, since I wasn't expecting to play my commander anyways. Then I made Gyniva, Obsessed Life Giver:

Since then, I've had the option of running her when I'm with players that haven't had a problem with custom cards. It's been great and I want to give everyone the same opportunity.
Share your favorite custom commanders that fill that niche you've been looking for, or, if you have an idea for a deck and need a tailor made commander, ask here, and I (and hopefully others) will try to make one that fits the bill.

For something even more niche, I love Charms (Commands, Confluences, etc. as well, but especially Charms). Currently, the only commander that has any meaningful interaction with charms is Ramos, Dragon Engine, so I'd love to see ideas for a modal-spells-matters commander.
(Also, I know it shouldn't be common. I meant to make it rare, but am too lazy to go back once I hit publish.)

In particular, I've been working on a commander deck for Zufina over here if it might interest anyone.
Still, I think it would be even more awesome to see a commander that is in all five colors and give some kind of pay off to as many of the various unique experience counter strategies as possible. Anyone want to take a whack at making something awesome for experience counter tribal?

EDIT: Lowered the additional cost to swap the P/T of creatures with different controllers.
