Roper

Defender
{2}{r}: Tap target creature, pay {e}{e}{e} extra and
the target creature does not untap their
controllers next untap phase.
A roper can hold still for long hours, shutting its single
eye to look like nothing more than a mundane
formation of rock. Creatures that come too close are surprised when that eye snaps open and sticky tendrils
shoot out to seize them.
