Ward — Sacrifice a land.

Whenever a land is put into a graveyard from the battlefield, return it to play under your control. It is
an artifact in addition to its other types and has:
"{1}, {t}: add {c}{c} or one mana of any color."

Roboticize — {c}{u/b}: Gain control of target creature an opponent controls. It is an artifact construct with: "Sacrifice this creature: gain life equal to this creature's toughness."
