Clearly we should bribe DougZ to implement Tanto Cuore instead.
Always kind of wondered how Arclight got away with it... Maybe because the cards are weaker and the game is therefore not quite as fun.
So it should be okay if isotropic is "Dominion, but not as good!"
They got away with it because the game is a really different variant if delved into. Base set Tanto Cuore and base set Dominion are really different game strategically even if some of the card effects are similar and the goal is similar.
I have Base and Expanding the House for Tanto Cuore, but aside from a little weirdness with private maids, chambering, and buildings, they really just feel like they could be a different expansion of Dominion (but of course, more expensive), certainly nothing as weird as the stuff coming in Dark Ages.
I guess I just feel like I don't have to adjust my thinking much to play Tanto Cuore (although I hear the same cannot be said of moe Nazi girl Dominion Barba Rossa, so I'm looking forward to that!)
