What happens if you use Thespian Stage to copy a creature that is affected by Imprisoned in the Moon or Song of the Dryads?
Thespian’s Stage will become a copy of whatever Imprisoned in the Moon is enchanted, as it was printed. It’ll be an exact copy of that card as printed except it will have the activated ability to become a copy of target land.
For example, if Imprisoned in the Moon is enchanting a Tarmogoyf and Thespian’s Stage targets the Goyf-land with its copy ability, then it will become a Tarmogoyf when the ability resolves. It won’t be a land and will be a green lhurgoyf creature with the ability that defines its P/T and “2, T: Tarmogoyf becomes a copy of target land and gains this ability.”
