Father and Mother N1089 and Medical ninja M485

[Atamasa]

Hello i have one important question.. if my opponent have in-play Father and Mother and i want play Medical ninja mission card..Can I play it and use it her effect ? I think that I Can, because Father and Mother says:Your "Sand" Ninjas are unaffected by your opponent's Ninja and Mission card effects. But Medical ninja mission says: Your Teams with 1 or more 'Medical' Ninjas can only be blocked by Teams with 1 or more 'Medical' Ninjas this turn. I mean that i dont affect opponents ninjas , I affect TEAMS... My teams who cannot be blocked by TEAMS without Medical ninja..I think that with Medical ninja mission card i make condition for battle ... Sorry for my bad English and thank you for your Answer
