Will the other Sentinel's be uncommon too? If not we could reference uncommon Sentinels. Referencing Relentless Hunter Androids seems a bit much to narrow it down to one figure without using it's name. I'm not sure how we are going to ever get away with having two different cards with the same name and no secret identity. Shouldn't any future Sentinels have a slightly different name similar to how Tony Stark has named his suits different things. So using the name Sentinel would reference to the ones we already have since that's the name on their card, then a future Omega Sentinel or Sentinel Prime or something would have a different name.
