Agrus Kos, Wojek Veteran, is a Boros Legendary Creature from the original Ravnica: City of Guilds.
At 3RW for a 3/3, he initially sounds fairly underwhelming. That is, until you read his ability:
Whenever Agrus Kos, Wojek Veteran attacks, attacking red creatures +2/+0 and attacking white creatures get +0/+2 until end of turn.
This more or less balances out his casting cost, giving you a 5/5 for 5 mana.
As far as actual Commander implications, he isn’t terrible, but I’d rather play Tajic, Blade of the Legion or Gisela, Blade of Goldnight over him most of the time. However, if you are playing entirely Boros creatures, he effectively makes every creature in your deck +2/+2 bigger each time you go on the offensive, making him a fantastic aggro commander.
The best example of this sort of deck is one that I found on MetaMox, which is becoming a go-to site for our Commander research here at Win Target Game. Besides being a fairly budget deck, this Agros Kos EDH list uses exclusivelycards that are both red and white with the sole exception of Rally the Peasants, which has a Red flashback cost. This allows Agrus Kos the ability to always have his troops at full strength and the various buffs pump more effectively for all creatures.
Things to play in an Agrus Kos Deck:
Outside of using him as a Commander, he is definitely a good play within other Boros decks lead by the other aggressive commanders like Aurelia and Tajic.
