Green Sun’s Zenith finds a green creature with mana value no greater than X and puts it directly onto the battlefield. That gives green decks one card that can serve as early acceleration, a utility search, or a late-game finisher depending on how much mana is available. Afterward, Zenith shuffles itself into its owner’s library for a possible future draw.
Choosing X equal to zero can find Dryad Arbor, a green creature land with mana value zero. That turns one green mana into an additional land on the battlefield, although Arbor normally cannot use its tap ability immediately because it is also a creature. At larger values, targets such as Eternal Witness, Collector Ouphe, or Oracle of Mul Daya provide different kinds of utility.
Craterhoof Behemoth is a possible finishing target when the deck has developed enough mana and creatures. The searched-for creature enters directly, so entry abilities work, but cast triggers do not occur. This makes Zenith especially useful in a toolbox whose creatures affect the game when they arrive or remain on the battlefield.
The target must be green, though it may have other colors as well. A colorless creature does not qualify simply because it is a staple in a green deck. Zenith also searches only the library, unlike Finale of Devastation’s additional graveyard option. Build a range of useful targets at different mana values so the card improves awkward early hands and remains relevant when the game reaches the stage where one precisely chosen creature can change the outcome.
