Do you mean the names like 'ruin' on the 10 of swords, and 'love' on the 2 of cups?
These are their names! Not taglines.
The 10 of swords is 'The Lord of Ruin'. It's it's name.
I love those names, and the ones that go with them, like the Fool being 'The Spirit of Ether' and the Tower being 'The Lord of the Hosts of the Mighty'.
I love them so much I could list the whole damn lot right here. (Though I won't.)
It's part of their heritage.
And why would you cut any cards!!!!!
That's almost sacrilige.
However, I have seen some cards pictured on the net where the writing seems to be in blue and the name of the card is almost obscured by the word behind it.
Unless it is just the reproduction that makes them look like that, you might find them better as they are hard to read.
