Every form of divination can be of used here. In general I tend to find it is helpful to use a system of divination that the specific Spirit you are trying to speak with knows.
Tarot is probably the first port of call for many western occultists. This isn’t necessarily going to be the best option. Especially if the Spirit in question is too old to have seen them, or did not work with them in life.
You might find a simple coin toss, Lot divination or even a pendulum is a simpler and easier way to build up language with a Spirit to get clear answers.
Most cultures have a concept of yes/no/maybe. Working with a divination system that applies to that style of questioning can help you get a ‘feel’ for the Spirit. Taking time to introduce yourself to each other.
A interesting point is that you can teach new skills to Spirits that you have built a relationship with. Usually in the space of post devotion and pre-dismissal, I will introduce new concepts. You could teach your Spirits tarot over time if you so desired, by showing them the cards and explaining their meaning.
After a period of time that you have built up a rapport with a Spirit. You could mix a small amount of their grave dirt into the Incense Of the Dead and perform an evocation to them to scry them through the incense smoke. But again this is something I would encourage further down the line once the relationship is built.
The key here is find a method that works best for you and your Spirits. Taking time to get to know one another and the style of communication that works best for you both.
May the Kindly Ones guide and bless you.
Love and Manyfold Blessings
