Land of Almost no Return
1p EX - Uncommon
All discarded cards are removed from the game.
Activate: Until the end of turn, this card does not remove discarded cards from the game.
Right now it can be used to counter sleepers kind of, or other Exiles decks. But other than that its not really useful.
Maybe if they made cards that comboed with removed from the game (other than the sparse defiant cards) this could have more of a purpose. Its 0 cost, but idk if its even worth putting in the deck, there are also no location combo cards. Would be better if this card had Exile.
The thing about making an Exile deck that puts in cards like MindBender, Mind Splinter, Chalice of Madness and etc., is that it's too unreliable as you never know if you might for example go up against sleepers. In such a situation a card like Mind Splinter is just a dead draw. That is why the card doesn't need to counter all factions. You can sideboard the card or to get rid of Land of Almost no Return as dead draw by adding cards with Overcharge. Plus you can add in cards with removed from game effects, that way the removed from game effect cards could combo both with the Overcharge and Land of Almost no Return(If you are discarding your own cards).
I just don't see any point in adding new cards that make the opponent discard cards if a faction like sleepers makes it unplayable. I totally see your point of the card being better by having Exile as you may also want to discard your own cards.
