Flying, haste
Consume Anomaly — Whenever Time Reaper deals combat damage to a player, put target face-up card they own in exile on the bottom of their library. If you do, you gain 3 life.
Most cards in exile are face up and can be targeted by Time Reaper's triggered ability. A card is face down in the exile zone only if the effect or action that put it there specifically says it puts it there face down (like the foretell ability).
Random a card of Magic: The Gathering (MTG), but you can also roll the D20 dice, random a Planeswalker, have fun with the random rules and more.
