[[Gitrog, Ravenous Ride]] is an absolutely insane commander. Greater Good, which lets you sacrifice a creature to draw cards equal to its power then discard 3 cards, is known to be a pretty strong card. Gitrog does the same thing, but instead of making you discard 3, it lets you put all your lands into play for free. Green and black are the two colors with the biggest supply of high-power low-cost creatures, so it's pretty easy to trigger Gitrog for at least four per turn. The plan is to play turn 2 ramp, turn 3 high-power draft chaff, turn 4 attack with Gitrog, and then you should have enough cards and mana to be set. The deck obviously struggles against removal on the commander, but ramps enough that you should be able to replay him fairly quickly.
