It prob wont work with Beckoner of Evil since its a battlecry and he wasnt in your deck or hand. Twilight Elder will prob buff it as its a effect every turn.
Because the C'thun buff has been explained as a player aura and not something applied to C'thun himself, then I would assume that all buffs from before he is gotten from portal would still apply even though he wasn't in your deck.
Its the same idea as mind control effects on him, and the fact that he can have different buffs if an opponent takes control of him
i.e. Because buffs are attached to player and not C'thun, it really does apply to him, wherever he is, even in a portal
If you play Beckoner of Evil and Twilight Elder, and in the following turn you play Unstable Portal and You get C'Thun, Will C'Thun have the buffs?
It said 'Wherever it is' I'm wondering if it works if he is in other dimension
