And speaking of forgotten gems how about that awesome awesome tag match between AMW and Team Canada (Roode & Young) from Final Resolution 2005. IMO, one of the best tag team matches in TNA's history. Team Canada is another tag team that gets overlooked quite a bit. They used to be pretty solid back in their day.
AMW vs. Diamond & Swinger (with Disco Inferno as their manager) was another tag feud that I don't see mentioned in this topic. That one was pretty good too.
