Forum:D.D. survivior & scout plane Q

When my D.D. survivor is face-up on my opponent's side of the field and is remove from play will it return to my field on the end phase? im asking this 'cause the second errata card of D.D. survivor said that the only condition is to be face-up on the field to return when it is remove from play.

the other thing is, why d.d. survivor and d.d. scout plane just can do their effect once per turn? if the card doesn't say once per turn, it say... when this card is removed from play special summon it at the end phase of this turn in the case of d.d. scout plane, for example:

player A has 1 set trap or spell card, and player B has a face-up macrocosmos and a face up d.d. scout plane.

player B normal summon cyber valley and actived its second's effect, and remove from play d.d. scout plane and itself,then player B draw 2 cards and end his/her turn. in the end phase d.d. scout plane is special summon in attack position.

Player A active torrential tribute and remove from play D.D. scout plane again

this is my question... it will return again in the same end phase or it will still remove from play? 'cause as i said the card text doesn't say once per turn
