Ruling Question: Is Junk Archer supposed to reset ATK/DEF values?

[Soulkey]

Played against AI using story deck.
I had a Earthbound Immortal Wiraqocha Rasca (base ATK/DEF 100/100, boosted stats were 3100/100). Junk Archer banished the card, and when it was returned by Archer's effect in the same turn, the ATK went back to the default 100.

Is that normal?
I mean it's obvious in cases like Dimensional Prison, Bottomless Trap Hole etc, where the cards are removed from play "for good" (figure of speech) that they have their ATK/DEF reset, but in Junk Archer's case the cards are returned in the same turn.

I had to get a specific ruling that was similar to this situation and now i can make my verdict.
Junk archer removes said monster from the field. As a result, this monster's atk and def are dependent on its effects. It only gets an atk buff if it stays on the field indefinitely and interaction with the monster that makes it no longer face up will reset its attack. When Junk archer removes Wiraqocha, it's like the monster "forgets" what happened before when it gets returned to the battlefield.
A similar effect can be reproduced if you skill drain it and at a later turn you remove skill drain. It forgets it ever had the atk buff. This is how atk/def interaction works in the game, they must stay on the field or they "forget" what their atk/def is supposed to be from their effects.
Banishing it and returning it, fliipping it face down(book of moon) and then back up, special summoning from grave, etc. are all ways where it had forgotten its attack buff and unfortunately in these cases, renders the monster useless.
So yep it's normal. It doesn't matter if junk archer or something else removes it, the atk buff is forgotten regardless of how it was removed and put back.

Thanks for the confirmation!
Cheers!

Yeah be careful with that one, the monster goes back to it's "base stat" written on the card as it no longer "existed" on the field and the above player explained it perfectly but yeah terrible situation to be in and this is from a fortune lady player who knows no effects means 0 atk -_-
