One thing to note about Volo, Itinerant Scholar (aside from all those creature types) is that it has an ability called "choose a Background." Choose a Background is a very specific version of the partner ability, which can allow a player to have more than one commander
Wood Elves 2.0 A card that has survived the culling of the elf deck to the B cube in which they would often generate you mana upon casting
Still amazing as a card in the 40 allowing you ongoing value and the only companion that is just a stand alone strong cube card that you would still play without the companion ability

I hope you think so too
