{T}: Add {C}.
{2}, {T}, Sacrifice Field of Ruin: Destroy target nonbasic land an opponent controls. Each player searches their library for a basic land card, puts it onto the battlefield, then shuffles.
If the target land is an illegal target by the time Field of Ruin's ability tries to resolve, the ability doesn't resolve. No players search for a basic land card or shuffles. If the target is legal but not destroyed (most likely because it has indestructible), each player does search and shuffle.
