Revitalize isnt a good card in Limited, but you dont feel that bad having to play it
My LGS has an entire weekly event called Commander Monday that separates players into random pods based on the strength of their deck
Theres also the contradiction of cards wanting instants and sorceries in the yard (Eris, Roar of the StormEris, Roar of the Storm, Octavia, Living ThesisOctavia, Living Thesis, Smoldering StagecoachSmoldering Stagecoach), and other spells wanting to take them out (Treasure CruiseTreasure Cruise, Bloodthirsty AdversaryBloodthirsty Adversary, Dig Through TimeDig Through Time, Arcane BombardmentArcane Bombardment)
Creatures that tap opposing creatures through means other than activated abilities cost more
Coupled with the fact that the Friendly Neighborhood Draft is available for two weeks, prices might not be too bad
Proxies may not be of the same quality as actual cards and may not shuffle or handle them as well
