RESCUSE RABBIT VS FIENDISH CHAIN /veiler !

This was quoted from wikia though Frm OCG part
Pls help verify !
Even if a face-up "Rescue Rabbit" is being affected by "Fiendish Chain", it can activate its effect. Furthermore, at the time of the resolution it is no longer affected by "Fiendish Chain" and you can Special Summons monsters from your Deck.[3]

true story

So ? Means regardless of situation , veilers and chain wont stop rabbit ?!

veiler can stop, demon chain cannot.

demon chain will only negate the effect if the monster is still on the field

rescue rabbit's effect can still be activated, thus as a cost removing it out of game first,
after so demon chain will not be on rescue rabbit anymore,
therefore allowing it to continue resolving its effect

Demon Chain and Skill Drain only negates monster on the field.

Effect Veiler negates a monsters effect fully during an entire turn if it resolves, but the target monster must still be face-up for it to resolve successfully.
