I have 3 controversial questions

[KaoticZexis]

1st two questions my friend and I debate over. last question is for my personal comboing

1.) Haku N-1311 effect states that you can remove a mirror coin from this ninja to change the target of a jutsu to another LEGAL target. If I am correct...any jutstu I activate that says "target ninjas battling the user" my opponent wouldnt be able to redirect that justsu to MY ninjas, their arguement being "well it says battling the user , so i am now using the jutstu" which is not correct IMO because haku's effect said nothing about him becoming the user . . . So my question here would be define "legal" to the best of your ability for me so that we could understand.

2.) Today my friend points Button Hook Entry J-457 and Clean Hit J-483 says the requirements are Sakura Haruno+Chunnin or Higher Rank or Tsnuade. He seems to think the "or higher rank part" is reffering to a possible 3rd user of this jutsu being...anyone in the game higher than rank Chunin....which i think when they say "or higher rank" that theyre further elaborating/reffering to Sakura ...which he thinks is stupid because there is no sakura that is higher than chunin rank. So who is right? Can any higher rank than chunin use this jutsu or is "or higher rank reffering to sakura even though there is no higher rank of her.

3.) If I have Orochimaru N-447 and Shikamaru nara NUS-014 in a team together, would that basically be attacking the players village directly always because shikamarus effects makes the head ninja of whom theyre battling an entrance cost of 0 and orochimaru cant be blocked by a team with a ninja who has an entrance cost of 2 or lower?
