If I'm running a kruphix edh deck and have a seedborn muse and a copy. Can I respond after the fist trigger and tap my land before they untap again?
Seedborn Muse’s ability isn’t a triggered ability. It’s a static ability that modifies what happens during other players’ untap steps. As such, there’s nothing to respond to and no way to take advantage of multiple Seedborn Muses this way.
(Also, players never get priority in the untap step anyway.)
