So I went through and searched each page of the thread for Worm Harvest. It looks like it didn't see a lot of showtime due to Birthing Pod, Deathrite Shaman, and Bob. Since Pod and DRS and both banned now and some lists aren't running Bob, it might be worth looking into again.
Trying to run a search on the thread didn't return anything (I think the search function is broken) but what about a fun of Worm Harvest? At the point of CCGGG we'll have 5-10 lands in our graveyard. That would allow for decent chumps against Tasigur, Tarmogoyf, and their ilk, or allow us to threaten to swarm and overwhelm after a couple turns.
