Gammahar Watchwarden

Cover {1}{r}{r} (If the cover cost is paid, Gammahar Watchwarden enters the battlefield attached to target
land you control. As long as it is in cover, it cannot
attack or block. Unattach it any time you could cast a sorcery by playing its mana cost.)
{t}: Target creature cannot block this turn. Use
this ability only if Gammahar Watchwarden is in
cover.
