1.) Can Manda N-1083 negate ninja effects outside of battle such as Inoichi N-1279. If so would that negate their effect pernamently since it doest specify until the end of the turn?

2.)If The First hokage PR-018 is a standy ninja could he activate Sealing the evil J-594 ? Or any jutsu at that? I thought stanby ninjas couldnt activate jutsus since they arent on the battlefield.

3. Can ninjas effects activate even though they are standby such as Pain (Preta Path) N-1004

4.) If i sacrifice Giant chameleon N-1001 for Pain (Deva Path) N-1619 or anything with a hand cost for that matter, would chameleons effect of returning to the hand activate in time for me to discard him as hand cost also?
