Tarot isn’t a game, they are a tool for guidance, insight, psychic & personal development as well as meditation.

You use the cards that are at the top of the deck once you have shuffled. You do not pick the cards.

As you are new to the tarot the Celtic Cross is best left as it is complex. A single card will be easier.

You should have cards with swords, wands, cups, coins, and other non-suite ones like The Sun.
Go to this website to learn more and how to read each individual card: http://www.paranormality.com/tarot_meanings.shtml

Also, if while you’re shuffling a card falls out of the deck, it probably means that card is wanting to tell you something, so just put it aside and read it after you finish the celtic cross.

Some people can use them and others can’t. You just have to get comfortable with your own individual deck and basically just have the knack for it because otherwise you get cards that are just wayyy off.

Personally, I’ve only had a few circumstances where I dealt them and the cards were actually right at predicting how the rest of my night turned out.
Honestly, I think the cards just read how you are feeling right then in there (like reading your sub-conscious), so if your mood changes throughout the day I think they could come out completely off.

They’re nothing to really rely on or are all that “freaky” as some people think. It’s just a nice occasional reflection of your current situation in your life — probably won’t show anything you don’t already know.

Aries actually rules the Emperor card, it is Uranus that rules The Fool card
Uranus’ brief description is Modern thought, Experimentation, New ideas
Where Aries is Active, Demanding, Determined, Effective, Ambitious- sounds more like an Emperor than a Fool

Here is a poem of the Fool in one of my plays in which the Tarot is an important part.

I be the Fool, though I do not drool,
as some around me do.
The tales I tell, from my lonely cell,
speak jabber wocky new.
High crystal road, when heavy strode,
breaks tinkling like a bell.
Then human minds, like old pork rinds,
do slowly go to gel.

As for a Significator, I use a separate deck and chose a card the I feel feels like where I am right now. I choose from the entire deck. I will also sometimes chose a card that show what I want to create in my self and use this as a final card. So I have a signigicator that I start with, drawn the cards for the spread, and place my chosen end card as the final card. I like to use a separate deck for a few reasons; the two main ones are:
1. I'm not removing a card from the readings in case it has something to show me, and if it does match one of my chosen cards I take that as having additional meaning and weight.
2. It gives me an opportunity to use a deck I may love the art of, but don't really use for readings.
I don't use significators for the majority of my readings.

You can of course add extra ritual to all of this, you can place the deck in the light of the moon the night before you do this. Message a special oil into your hands before starting, I use sandalwood. Light a candle. Say a prayer. Do a calling ritual. Anything that fits with your spirit and feels right. None of it however is necessary. If you think the deck is yours it is.

I teach tarot & have Yahoo Group (link below) will always help if I can.

With that in mind im not sure what you mean by 'keying'?

Significators are a matter of choice, some do not like to take an important card from the deck. A significator doesnt always have to be a court card either.

From a court card pospective you can use them from an astrological, colouring or personality view point. Make sure that you only choose one if your new to tarot or it can get confusing.

sorry…having a bad night.

Let me just say, I've met a lot of people who went to psychics who gave them otherwise great readings, where it was predicted that their great wish (often involving an ex) would come true at such-and-such a date, and it never happened. The person often continues holding onto the hope for years, too.

That said, I've had readings myself where what the prediction stated seemed unlikely and ridiculous at the time it was made, but also came true just as the person had said.

So in short, it is *possible.*
