What will happen with triggered ability of Deputy of Detention on a stack? According to the rule 702.25b cards which are phased-out cant affect and be affected by anything in the game:
If a permanent phases out, it's 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.)
last weekend I've got in a dispute about phasing. I had in play Teferi, Master of Time, opponent casts Deputy of Detention and target's Teferi, Master of Time.
Now, I used Teferi, Master of Time ability: minus 3: Target creature you don't control phases out.

So what my opinion about this is:
Deputy of Detention enter's battlefield, target's Teferi, Master of Time
Teferi, Master of Time uses minus 3 ability targets Deputy of Detention
Nothing else is added on stack.
Teferi, Master of Time minus 3 ability resolves. Deputy of Detention is phased out.
Deputy of Detention ability resolves. It's phased out and according to rules it is treated as though it didn't exist (aka same situatuion, If I destroy Deputy of Detention) and it can't affect and be affected by anything in game.
My friend tried it in online Magic the gathering: Arena, where behaviour is that targeted permanent is exiled, even it's phased out.
What's your opinion on this?
