The official ruling of Promise of Loyalty states: "Each player, including you, must put a vow counter on a creature they control if able. They can't choose to opt out and sacrifice all of their creatures."

However, on MTGO it gives players an option to click "No" when it's time to assign a vow counter, allowing them to sacrifice all of their creatures. This bug caused me to lose a game because my opponent was able to sacrifice their single creature on their board (their commander), and recast it on their next turn to attack me with lethal damage. 

I am getting really tired of losing to bugs on mtgo. I've submitted this one on their official forums, but if anyone with the power to fix it sees this please do so, as it's a very big oversight.

I start to feel bad if I win more than once during EDH night at my LGS, so I want to be able to switch to a deck that is all about helping the underdog at the table - all while keeping myself alive.

I also wouldn't mind having a sideboard of cards to swap in if I want to play it to win, with the strategy of surviving until it is just the two of us before activating a wincon with cards such as [[Insurrection]], [[Reins of Power]], and [[Inkshield]].

Here is a deck list of what I have come up with so far, though I'm thinking of switching to a wider color scheme since two of the wincon cards mentioned above don't currently qualify.
