Animate fanning cards almost works!

I have a list of cards set with a starting and ending position. When I simply place the cards, they are placed in the scene as a fanned-out deck. Like so:

I want to animate this so that the deck of cards moves along the angle and the cards drop into place to create the final look. For the most part, I have a function that does this, but I am having some conflicts with proper placement. Here the designed function.

I would also like to know the best way to turn the cards while they move along the arc. Thanks!

     IEnumerator AnimateCardSpread()
     {
 
         Vector3 newPos=memoryCards[0].startPos;
         int k=0;
 
         while(k<memoryCards.Count)//memoryCards is the List of card objects with established start/end positions
         {
             foreach(CardController c in memoryCards)
             {
                 //has the card reached it's endPos? 
                             //I THINK THIS IS WHERE THE PROBLEM LIES
                 if(c.endPos == newPos)
                 {
                     c.transform.position=newPos;
                 }
             }
 
             // calculate current time within our lerping time range
             float cTime = Time.time * 10f;
 
             // calculate straight-line lerp position:
             Vector3 currentPos = Vector3.Lerp(memoryCards[k].startPos, memoryCards[k].endPos,cTime);
             //Vector3 currentPos = Vector3.Lerp(new Vector3(-4,0,0), new Vector3(4,0,0), cTime);
             
             // add a value to Y, using Sine to give a curved trajectory in the Y direction
             currentPos.y += animSpeed * Mathf.Sin(Mathf.Clamp01(cTime) * Mathf.PI);
             
             // finally assign the computed position to our gameObject:
             newPos = currentPos;
 
             k++;
 
             yield return new WaitForSeconds(.02f);
         }
     }
