I fully expect people to recant their praise for these cards to some extent, but if instead they double down - then good on them I guess.
Personally I think the opposite will happen where people weren't as accepting to the MDFC cards will open up to them more. Granted, I do think some of the more narrow MDFC cards like Glasspool Mimic will come and go, but I think a good amount of the mythic MDFCs and some of the non-mythics like the elephant are here to stay for a while.
I'm struggling to understand how they give you more options since you are literally forced to pick only one.
Shelldock Isle literally only has a single mode. Sure, the land mode does two things, but you can only ever play it as a land and you can't use its ability until next turn, assuming the 20 card library condition is met. MDFC spells aren't pigeonholed into being played solely as lands, and their spell half take effect immediately.
Also, MDFCs typically have much more synergies than regular non-basic lands since there are far more creature / spell synergies in cube than there are land synergies.
At the very least, I think we can agree all these modal type lands are very far behind something like Shelldock Isle, where you can have your cake and eat it too (get the land immediately and cast something for free pretty easily in a proper cube deck)
I wouldn't speak for everyone if I were you because I think Shelldock Isle is medicore at best and is super overrated and know a good amount of others who share similar thoughts. While I MDFC cards are narrower than I'd like them to be, I prefer most of them over Shelldock Isle since it they give you more options.
