Are the money rare cards that have been printed so far in both Modern Masters sets expected to never see a standard reprint again? I think that's whack if so.
It's not necessarily true, but very unlikely. They have no problem reprinting expensive cards into standard (Thoughtsieze was close to 80 bucks before the Theros reprint, Mutavault was 50 before M14), but in the cases of a lot of cards, they are either too powerful to print into standard (Dark Confidant, Cryptic Command), some flavor-wise can't be reprinted in most sets (Vendillion Clique), and others are cards they have decided make the game too unfun (Blood Moon).
Tarmogoyf is the one case where it is not too powerful to reprint into standard, but the secondary market value might scare them off..
It was good back then, and would be even better now and warp the format to force them to print much more universal cheap removal.
In an format where there are no Fetchlands, A goyf will usually be a 3/4 (Creatures, Sorcery, Instant), with the potential to grow to 5/6 (Planeswalker, Artifact). It would be strong, but not as strong as, say, Siege Rhino is right now
