Forum:Zombie world+Lady In Wight+Type:??? 3 star

Okey, I got an question. If you would have zombie world activated on the field and have summoned Lady In Wight AND an Fiend type lvl 3 or less Monster. Zombie world makes all the monsters on the field and the graveyard to Zombie type monster and Lady In Wight Has an effect that works like this, All lvl 3 or less Zombie type monsters on the field are unaffected by spells and trap, Except Lady In Wight. And if Ill summon an Fiend type lvl 3 or less on the field, Then the Zombie world will make it into an Zombie, But What happens with Lady in Wights effect? Does it create an loop that works like this Fiend -> Zombie -> Fiend -> Zombie -> Fiend, And so on. This loop triggers by the Lady in Wights effect to make the Zombie lvl 3 or less Unaffected by spells and traps, And that does that Zombie world can't keep it as an Zombie anymore so It will return as an Fiend type lvl 3 or less, But then it isn't immune to spells or traps so it will be affected by Zombie world.

So, Does it become an Zombie monster or does it stay as an fiend monster or perhaps both?
