Ah yes, my favorite 3 color combo in Magic. I think RUG my favorite, it might be BUG though. Forced to choose, I would take RUG so I thought this guy would make a great Commander for my latest deck.
I have had a hard time really grasping Commander as a format, always feeling like my decks were either too good or woefully underpowered. Finding the balance is really tough it turns out.
One thing I really like about Commander though is the deckbuilding process. I get excited to play with all these cool old cards, and getting a sweet altered Commander to get things going is a great place to start in my opinion :)
I did this alter on the magic cruise, but I found a pretty calm part of the ship to paint on and had a great experience painting and hanging with people finishing a cube draft and such. I'll always have a good memory of that to associate with this alter.
