Lets say I have in play kushina (n1116) and shima (n1301). My turn marker is at 5 and i play the sage returns m830. Could i put in play Gamabunta (n1591) because of kushinas (n1116) effect?

Now i play m804 the following turn when none of my ninjas previously mentioned have left play. Would I draw 4 cards or just 2?

now lets say I didnt have n1116 and when my turn marker is at 7 with n1301 on the field. I play m830 to bring n1591 on the field, would i have to card cost?

only puts the Ninja you searched for in play if its Entrance cost(EC) is less than your Turn Marker. With in play, the EC of would be 5. Since its EC not lower than your Turn Marker, it would not be put in play.

You would draw 4 cards with because n1116 only affect out of play Ninjas.

You would not be able to put n1591 into play. But if you could, you would not have to pay the hand cost.
