Mirrodin Besieged: Green Sun's Zenith

Green Sun’s Zenith from Mirrodin Besieged is a powerful green sorcery that has had a huge impact in formats like Commander, Legacy, and Modern (when it was legal). Here's the breakdown:

Green Sun’s Zenith

• Mana Cost: {X}{G}

• Card Type: Sorcery

• Text:

  Search your library for a green creature card with mana value X or less, put it onto the battlefield, then shuffle your library.
  Shuffle Green Sun’s Zenith into its owner’s library.

Why It’s Good

• Tutoring Power: Lets you grab exactly the green creature you need — whether it's a utility creature like Scavenging Ooze, a mana dork like Dryad Arbor, or a bomb like Craterhoof Behemoth.

• Instant Board Impact: The creature comes straight onto the battlefield, not your hand.

• Recyclable: Unlike most tutor effects, Green Sun’s Zenith shuffles back into your library, so you can draw and cast it again later.

• Legacy Staple: Often used to fetch Dryad Arbor turn 1 for ramp.

Common Synergies

• Dryad Arbor: With X=0, you can grab it turn 1 for ramp.

• Birthing Pod decks / Toolbox builds: Pull exactly the right creature for the situation.

• Elfball / Mono-Green Ramp: Access to ramp creatures, combo pieces, or big threats.

Format Legality (as of my last update):

• Commander: Legal (staple in green decks)

• Legacy: Legal

• Modern: Banned

• Vintage: Legal

• Pioneer: Not legal (never printed in a set legal for Pioneer)
