On the other hand, a high cmc deck that wants to win on turns 10+ will want a higher land count so you can consistently hit your land drops on turns 5+
But unless your deck is already geared toward other strategies that also take advantage of these cards, trying to refill a spent Iceberg is gimmicky at best, and an inefficient use of mana at worst
It prevents opponents from casting spells at instant speed, making it difficult for them to respond to your plays
But on top of that, as sets stop being produced, cards become rarer, further increasing a card's value
More often than not, this makes Lair Of Darkness a useless extra card in one's deck that cannot be activated, and thus it is considered overrated
