My advice is to dedicate 5 to 10 minutes to practice combos.
Take the deck and shuffle.
Then take 1 card from the top and put it on the table. Think of the meaning and keywords.
Take another card from the top of the deck and put it on the table besides the previous one. Think of the meaning and the keywords
Now read them in combination.
For instance: Tower + Letter = A place + Mail = Post office.
Continue by taking 1 card and put it on top of the first card and then another one and put it on top of the second card you took before. Read them in combination.
Repeat this until you run out of cards.
If you want to continue practicing after having read the 18 combos then take 1 card from the top and put it under the deck. Now start it over.
Reading combos will become soon second nature.
You might sound silly but it is important to say the keywords and the combos meaning outloud.
