Hi my question is with modern spirits, say i use life spinner to sac 3 including a spirit with soulshift to bring out iname death aspect, my question is with how this would play out and if the spirits dumped with iname entering play are valid targets for soulshift
When you cast a spell or activate an ability, it goes on the stack before any of its costs are paid. Anything that triggers due to the payment of those costs goes on the stack above the original spell or ability and will resolve first.
In the scenario you describe, the soulshift ability of the sacrificed spirit(s) will go on the stack above Lifespinner's ability and resolve before it does, meaning that Iname is still in your library at that point and thus hasn't yet put any spirit cards into your graveyard.
You can, however, target one of the other spirits you sacrificed to active Lifespinner's abiliity with the Soulshift.
