Threaten Hostage

Enchant target creature your opponent controls.
At the beginning of your opponents upkeep
destroy the enchanted creature unless its
controller taps two lands and taps this creature.
The enchanted creature cannot untap or activate
its abilities until end of turn or you may search
your library for three basic land cards and put
them onto the battlefield tapped if you do exile "Threaten Hostage".
"Please my Lord give me my life."
