I was actually thinking of narrowing down the list, and basing it off of TC's Chariot Race Rules, but allow the players to influence it in a RPS fashion, and then rolling dice based upon valor.

Thus, in the following fight, we have two knights

Knight Cecil has 2 HP, as dictated by his avatar, and 6 valor (3 silver chevrons), which would give him 3 dice per phase.

Knight Flax has 4 HP, as dictated by his avatar, Fine Armor, and Hypochondria, with 4 valor (1 silver chevron), giving him 2 dice per phase.

Knight Cecil has the trait "Scout", giving him the opening move - he chooses attack, and his stance type - High, Mid, and Low - Mid.

Knight Flax chooses his stance type - High, Mid, Low - Low

Spoiler Alert, click show to read: 
Low>High>Mid>Low for reference, with the superior stance gaining a +1 bonus to all it's rolls


Knight Cecil rolls 4, 1, and 5, and each die gets +1 due to his superior stance, giving him rolls of 5, 2, and 6

Knight Flax rolls a 4 and 3 - not enough to beat either of Knight Cecil scores. Knight Flax is soundly beaten this phase, losing 2 HP.

Knight Flax then goes on attack, rolling 4 and 3 yet again, this time with Mid as his stance.

Knight Cecil defends with 4, 6 and 1 with his stance set to High, giving him advantage, with 5, 7, and 2.

Knight Flax is unable to damage Cecil, who is fighting superbly and easily countering everything being thrown at him.

Knight Cecil then launches into his own string of attacks - 5, 4, and 5 - with his stance set to Mid.

Knight Flax flounders under the withering series of blows - rolling 1 and 1 - and even screws up his stance, having it set at Low, giving Cecil +1 to his attack (6, 5 and 6). Knight Flax loses 2 HP, is on his knees, and is at the mercy of Knight Cecil's masterful handling of combat.

Okay, yes, a bit cheesy, BUT, this was all decided by random.org, so blame chaos if you so wish. This is the very basic setup, and the only current changes I am thinking of is "expanding" upon the idea of chivalry and knavery actions, and having every 3 chevrons add another die and hitpoint.
