Only reason I feel the Foil is rarer than the Timepiece (which I just received for the first time last week) is that people generally get the Gorgon cp, then run through the end, giving them a chance at the Timepiece, but not the Foil. There seem to be a lot fewer fresh runs than runs that start at the Gatekeeper for VOG. I also rarely see an Oracles cp advertised on the recruitment section of these forums. The most common cp's posted are either Templar, Gatekeeper, Gorgons, or Atheon, all of which exclude the chance to get a Foil while including a chance to get the Timepiece. As one person posted earlier, Supremacy is actually probably rarer than the Foil as it was only available for one week.
