Seedborn Muse is one of those cards players keep asking about. Here is, in plain words, what its official text says, the rulings published by Wizards of the Coast, and the combos players actually run.
Official card text
Untap all permanents you control during each other player's untap step.
Complete guide
Seedborn Muse is a powerhouse in multiplayer formats, ensuring that your resources are always available. By allowing you to untap every permanent you control on your opponents' turns, it effectively multiplies your mana and utility for every round of play.
What It Does
Seedborn Muse has a static ability that modifies the untap step of every other player. Instead of just the active player untapping their cards, you also untap all permanents you control. This includes lands, creatures, artifacts, and enchantments, regardless of their status.
How It Resolves
The effect happens automatically during the untap step of each opponent. This is not a triggered ability, so it does not use the stack and cannot be responded to. If you have multiple cards with this effect, they are redundant; your permanents simply untap once during that step. Note that you have no choice in the matter; all eligible permanents you control will untap.
Common Mistakes and Restrictions
A common misconception is that Seedborn Muse bypasses all 'does not untap' effects. While it bypasses effects that specifically mention 'its controller's untap step,' it will not untap permanents affected by general restrictions, such as a permanent with a stun counter or an effect stating it 'doesn't untap during untap steps.'
When to Play It
This card is best utilized in decks with high-cost instant-speed spells or mana sinks. Because it refreshes your mana every turn, you can cast threats on your turn and still have full mana for counterspells or activated abilities during each opponent's turn.
Interaction examples
Solemn SimulacrumIf you play Solemn Simulacrum and search for a basic land, that land enters the battlefield tapped. However, once your opponent's untap step begins, Seedborn Muse will untap that new land immediately, allowing you to use it for mana much sooner than usual.
Roaming ThroneIf you name 'Spirit' for Roaming Throne, it will not affect Seedborn Muse because the Muse's ability is a static ability, not a triggered one. However, both cards work excellently together as Golems; Seedborn Muse will ensure Roaming Throne is untapped and ready to use its Ward protection or block during every opponent's combat phase.

How it works : Seedborn Muse
Original English text — Wizards of the Coast / Scryfall
- #1· Wizards of the Coast
All your permanents untap during each other player's untap step. You have no choice about what untaps.
No other card is named in this ruling.
- #2· Wizards of the Coast
Other effects can prevent a permanent from untapping during an untap step. You do need to look carefully, however, as many effects say that the permanent does not untap during its controller's untap step, and this card's ability occurs during other players' untap steps. If a card does say this, then Seedborn Muse can untap it. But some other abilities are not written this way and can still prevent a card from untapping.
No other card is named in this ruling.
