Sedris, the Traitor King Ruling Q

[benjameenbear]

Hi there! So I have Sedris, the Traitor King in play and I have Thassa, Deep-Dwelling in my 'yard. Since Thassa is a creature in every Zone besides the battlefield (where her devotion clause becomes relevant), I assume that I can Unearth her via Sedris' ability.

What would happen if I Unearth Thassa and don't have the devotion to make her a creature? I assume that the Unearth ability still registers and she'll be exiled at EOT (since she won't be able to blink herself)? Or will the Unearth ability fizzle since Thassa is no longer a creature due to lack of Devotion?

You still exile Thassa at turn's end or if she leaves the battlefield some other way. The delayed triggered ability of unearth only cares that it's the permanent returned by an unearth ability, not what permanent type it is.

What if she's phases out?

What if she's phases out?

That's not leaving the battlefield, so the side effect of unearth won't do anything.

702.25d The phasing event doesn't actually cause a permanent to change zones or control, even
though it's treated as though it's not on the battlefield and not under its controller's control
while it's phased out. Zone-change triggers don't trigger when a permanent phases in or out.
Tokens continue to exist on the battlefield while phased out. Counters remain on a permanent
while it's phased out. Effects that check a phased-in permanent's history won't treat the phasing
event as having caused the permanent to leave or enter the battlefield or its controller's control.

702.83a Unearth is an activated ability that functions while the card with unearth is in a graveyard.
"Unearth [cost]" means "[Cost]: Return this card from your graveyard to the battlefield. It gains
haste. Exile it at the beginning of the next end step. If it would leave the battlefield, exile it
instead of putting it anywhere else. Activate this ability only any time you could cast a sorcery."

If she is still phased out in the end phase, the delayed trigger "Exile it at the beginning of the next end step." will not exile her (and will not trigger again).

702.25b If a permanent phases out, its status changes to "phased out." Except for rules and effects
that specifically mention phased-out permanents, a phased-out permanent is treated as though it
does not exist. It can't affect or be affected by anything else in the game.A permanent that
phases out is removed from combat. (See rule 506.4.)
