Until end of turn, creatures you control get +1/+1 and creatures your opponents control get -1/-1.

Zenith Flare deals X damage to any target and you gain X life, where X is the number of cards with a cycling ability in your graveyard.

The owner of target artifact or creature with mana value 1 or greater shuffles it into their library. Then that player discovers X, where X is its mana value. (They exile cards from the top of their library until they exile a nonland card with that mana value or less. They cast it without paying its mana cost or put it into their hand. They put the rest on the bottom in a random order.)
