Zymytolo, Shifter of Worlds

Eldrazi creatures you control get +1/+0 and gain wastewalk (a creature with wastewalk cannot be blocked as long as defending player controls a waste).
{2}{c}{c} Target land an opponent controls becomes a waste with {t}: add {c} until end of turn, it loses all of its other abilities and types until end of turn.
terrible to play hide and seek against.
