A Legendary Minion lord! Not that minions really needed much of a lord, as there’s less than 2 pages of them on the gatherer. Balthor the Defiled for 2BB is a 2/2 with 2 abilities. His first ability is his static ability, giving your minion creatures +1/+1. Sadly, Minions are a rather old type, the most recent being a blue creature from Ravnica. However, his other ability is very good; for BBB, you can exile Balthor the Defiled to return all black and red creatures from all graveyards to the owner’s battlefield. Sadly, this isn’t a great attribute in Commander, as it’s each player, and you won’t be able to take advantage of bringing back red creatures, as he is a mono-black commander. I’d certainly play him in a Red/Black deck, however. Or even Grixis; River Kelpie combos well with him, letting you draw a card for each creature entering the battlefield under your control.
Balthor the Stout is a 2/2 for 1RR, and has been errata’d a little bit:
Other Barbarian creatures get +1/+1.: Another target Barbarian creature gets +1/+0 until end of turn.
