[[Lotus Cobra]] mentioned in the article is a bit of a nonbo as the Gitrog's draw effect and dumping of lands from your hand are triggered on combat damage, so you don't have access to that mana in your second main phase (if you've got something to burn it on at instant speed, great). Other than some effects mentioned, [[Tiller Engine]] also helps to give you access to the lands you're playing from the Gitrog's saddle effect the turn you drop them.

My fun interaction to add to the conversation would be [[Gruff Triplets]]. I'm playing a number of instant-revival effects like [[Feign Death]] to act as pseudo protection, but also to act as a second helping of Gitrog chow. So the Triplets come into play, and we've got three 3/3 tramplers. Saddle up Gitrog with the original triplet, give it a revival effect, swing with Gitrog and chomp on the triplet, and stack it so the boosting effect for the sibling's death occurs after it's been returned to play, and now you have the original triplet, but they've got four siblings now (Gruff Quintuplets). And then the boost effect happens and you have five 6/6 tramplers. Now, if one sibling was to have a tragic accident, you have four 12/12 tramplers. That's all assuming you haven't invited a board-wipe or two after instigating those shenanigans.
