Fear the Day

Flying : Non-Wall creatures the active player controls attack this turn if able. At the beginning of the next end step, destroy each of those creatures that didn't attack this turn. Activate only during an opponent's turn and only before combat.

Fear (This creature can't be blocked except by artifact creatures and/or black creatures.) Whenever a creature deals damage to you, destroy it. When Dread is put into a graveyard from anywhere, shuffle it into its owner's library.
