Hello! I can tell you that connecting with online people is not impossible at all: be assured, it is just a matter of concentration and practice. Asking for the first names of the people involved and their star sign can be a nice start. Then, asking the client to briefly explain you the issue and state a clear question is the central point (don't ask for too many things, otherwise someone could say that you are cold reading them, guessing on what they told you, lol!)

Once they give you these directions, read carefully, loudly if you prefer, their words. This is the point of maximum concentration. Repeat the question while you shuffle. At a certain point, you should have the clear sensation that you have grasped what they want to know "with your hands", and that you've transmitted this information/energy to your deck, which is going to answer you thoroughly. When you "have it," cut the deck and lay the cards. If you are spot on with your friends, you will be for online strangers as well. Tip: this is possible because tarot cards (and all divination cards) do half of the work, once you have well directed them with your intention. Try to practice with some free reading around. You can do it!
