Temporal Rift

Anomaly 2 (This card is a basic land. It enters the
battlefield untapped with two distortion counters on it.)
Fortify non-artifact land {0}
Fortified land has phasing and shroud. When it
phases in, put two distortion counters on target
Rift. If Temporal Anomaly has more distortion
counters on it than target nonland permanent's
converted mana cost, tap that card and it phases
out. Otherwise, add one silver mana to your pool.
