Seedborn Muse
Creature — Spirit
Untap all permanents you control during each other player's untap step.
"The land echoes our intentions, and the kami echo the land. We must strive to live in harmony with the world even when it seems to rise against us." —Diary of Azusa

All your permanents untap during each other player's untap step. You have no choice about what untaps.

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.
