This land enters tapped unless you control a Plains or an Island.
{T}: Add {R}.
{3}{R}, {T}: Exile the top card of your library. Until the end of your next turn, you may play that card.

Tarkir: Dragonstorm

You must already control a Plains or Island as Cori Mountain Monastery enters for it to enter untapped. If it enters at the same time as a Plains or Island when you control no other Plains or Islands, it will enter tapped.

You pay all costs and follow all timing rules for cards played this way. For example, if the exiled card is a land card, you may play it only during your main phase while the stack is empty.
