4 rulings from Wizards of the Coast
- 4 October 2004If you cast a spell or activate an ability that lets you put a land onto the battlefield, the effect fails. You'll still do everything else the spell or ability tells you to do, such as shuffle the library.
- 4 October 2004Land can't enter, so an effect that "puts a land onto the battlefield" won't do anything, and the land will stay where it is.
- 1 May 2006In Two-Headed Giant, triggers only once per upkeep, not once for each player.
- 1 August 2008If a permanent spell tries to enter as a land during its resolution (for instance, a Clone entering the battlefield as a copy of a Dryad Arbor or an animated Mutavault), it is put into its owner's graveyard instead of entering. It never enters, so abilities that would have triggered on it entering won't trigger.
