Don't they usually come into play tapped for effects like this? Or is that only when it affects the caster
If it can destroy someone's land and just really ruin their amount of mana available that turn (which means it can be done on someone else's turn), it will usually make the incoming land enter untapped.
Think Demolition Field and Field of Ruin, or NEO Boseiju.
Krenko's Buzzcrusher has the land enter tapped, but it's usually being played at sorcery speed.
It's a pretty powerful effect already. The basic entering tapped would make it too powerful.
