This is a tricky card in this reading, for me the Magician isn't a naturally emotional card but it is a card where the person has the control of all the elements, they can manifest what they want.
I think that it's not an instant connection, there isn't a soul mate type connection where it gets deep really fast and they just get on, it's not magical where they don't know why they get on so well. This needs work! That is the Magician for you, they can make the emotional bond happen but they have to work out if they want to do it and the method? This can get a little sinister though because the negative side of this is they could manipulative or even fake the connection for their gain.
If they are spending long hours on the phone forming the connection, that is almost like a manipulation to make it happen, not necessarily a negative thing (just make sure the other person isn't being played) but it's not a natural connection to happen, it's manipulating the person to get closer, the Magician is ultimately an illusionist. However this bond is a choice or a plan of action if that makes sense. They might want to get closer to the person so they do lots to make it happen!
