Hi AngelDeck87,
I do not know what angel cards are per-se. I know they must be a tarot deck and I am familiar with using Tarot cards.
I suppose further explanation may be of help. First are there any keywords or messages for the cards? There also may be or should be a small instruction manual that may come with them if you bought them? Like I said I am not particularly familiar with this certain deck, but most decks do come with a basic manual and if lucky a general interpretation for the meaning of the card drawn either on the card or within the manual.
The manual also if I am not mistaken may have a couple spreads within it, that show how to lay out the cards in the preferred manner.
What many when starting out with tarot or a new deck do, is lay out the cards in a way of their choosing especially if the deck and paper does not contain any sort of lay outs and spreads, and then the reader, reads the cards by flipping them, looks at the general keywords or meanings of the cards, and gets a feel for the general reading.
If the cards have no keywords or meanings at all whatsoever on them, what one would do is simply lay out spreads and do readings, and pay attention to the feelings that come up for the reader regarding the reading.
Keyword here is practice. Once one begins to either read for others or themselves, they will in time come to see patterns with the cards.
Example my deck is a gypsy witch deck- the cards have short descriptions. I do not always look at the descriptions. After a while of getting to know the cards and how they come up (Like are placed) during the spread you come to rely on what you feel about the card set up itself and come to rely less upon the general descriptions on the card. Have faith and rely on your gut intuition. Practice and have patience with yourself. You will get the hang of it.
So as for my example within my spread I had the coffin card, the dark cloud card to the right of it, and the boat or sail boat underneath or above and to the left the scythe. The meanings on those cards indicate that the coffin next to the scythe is death. Literally this is what the cards say.
I studied the cards and felt- that irregardless of any death- that the card set up was indicating a sailing accident.
My parents and I were to go boating that upcoming weekend. We still went. We were sitting on the boat and I brought up the tarot reading I had done for myself, and was relaying to them how funny it was that the card set up looked like a sailing accident. Well my father asked me how I knew this and we started talking about feelings and intuition. After we talked I commented that obviously my feelings on the card spread must have been wrong because we had been out on the river a couple hours and nothing had happened and we were fine.
As my father tried to start up the engine on the way back, it wouldn't start. He tried to start it a couple times and it wouldn't start, he tried one last time, and the engine lifted off the back of the sail boat- the engine did not fit well with the build of the boat- and then it was all over. We lost the engine to the vast waters of the river.
Needless to say my father was quite upset. It was my brother's engine that my brother had purchased and was letting my dad use.
We ended up having to radio in and get a tow back.
There was never a death as the card meanings indicated- unless you count the engine haha- no it was as I thought, a sailing accident or disruption.
My point is, even if there is no clear meaning written anywhere about the cards, that you can still read them and be better for it, on your gut instinct and feelings. It is very good to practice reading with the cards and see how they feel to you, how the images feel to you. What do they say to you?
In time you will come to use the general descriptions as a learner's basis to go off, and your intuition and your sixth sense will begin to provide more of the details.
Hope this helps if only a little,
Like I said I do not have any experience with this particular deck of which you speak.
Good luck and all the best.
