This is the topic to talk about rare Mega Bloks/Construx figures and sets you own, you used to own, you just purchased, or you are looking for. I know most people (including myself) will probably talk exclusively about Halo Mega stuff, but that shouldn't stop you from talking about much older and rarer products. You can talk about sets that were intentionally rare (like the Halofest Rockethog) or you can talk about sets that were rare because of #ThanksDistribution. Or, you can use this topic to figure out what the rarest set you own is.
Here are a handful of my numerous "rare" sets:
1. The COD pre-buyout troop packs. These sets were only released for a short while with five figures before the later batches were dropped to four figures. Notable examples are the astronauts pack and the COD Ghosts pack.
2. Covenant Strike (the green Troophog). One of the more common "rare" sets, but rare because of two facts: It's hard to find online and it isn't listed as an official set (nor was it listed as an official set on the no longer up halomegabloks website).
3. The magnetic armory set with the orange Spartan, orange EVA, and the Orange ODST armor sets. This set is rare to the point of obscurity.
