little question on a rulling!

if u use that would i just get the control of the other monster?

i would personally say that you could do that, only because his effect doesnt say that he cant be targeted by a card effect, only that he wont be affected by spells or traps.

but that is my own personal opinion and how i see it. there may be something about creature swap that i might be getting

seeing as odin is unaffected by spells or traps, I think that you couldn't even choose him for creature swap(since choosing is part of the effect) and therefore u can't swap him.

That depends who controls Odin and whose turn it is. Note that Odin is only unaffected by spell or traps if the controller uses the once per turn effect, and it only lasts until the end phase. If you activate Odin's effect an then target him for Creature Swap (idk why the hell you would do that), that's an illegal move. If you do this next turn on your opponent's Odin, you can swipe it bc the effect expired at the end phase

quick question that relates to the same general effect, but a bit off topic since it looks like the original question was answered and i dont feel like making a new topic.

i think you just answered it in your last post, but when can you activate "once per turn" effects, such as this, or the shien synchro effect? its pretty clear when a card says "once per turn during either players turn", but what about when it doesnt state it?

im asking it here cuz i would think that there might be a chance that he could use the effect on his opponents turn to chain to creature swap

1) You can choose Odin with Swap, but since it cannot be switch control, all Swap's effect disappear.

2) Shien has effect that negate activation of another cards --> Spell Speed 2. Spell Speed 2 + "Once per turn" = "Once per either player's turns".

Excuse me, sorry for a newb question. "Remove from the field" and "leave the field" both r the same right?

Yes they mean exactly the same thing. But if you ever again need to ask a question for a ruling, please don't bring back a several month old thread, just post a new one in the Rulings section of the site.
