Archelos, Lagoon Mystic
Legendary Creature — Turtle Shaman
As long as Archelos is tapped, other permanents enter tapped.
As long as Archelos is untapped, other permanents enter untapped.

Rulings
Archelos's abilities don't apply to itself as it enters the battlefield, nor do they apply to any permanents entering the battlefield at the same time.
(wotc • 2020-11-10)
If more than one Archelos is on the battlefield, the controller of an entering permanent chooses how to order the replacement effects.
(wotc • 2020-11-10)
If another replacement effect says that a permanent enters the battlefield tapped while Archelos is untapped, the entering permanent's controller chooses whether the permanent enters tapped or untapped. If a permanent is simply put onto the battlefield tapped without a replacement effect being applied, it always enters untapped if Archelos is untapped.
