Hello Pegli,
ah! That's your question! I see.
Okay, I use your terms:

Correct, right, exactly so
Pegli hat geschrieben:I could use them for moving a curse card in their same column (of course if it's just behind them)
No, wrong, that's forbidden

It's only allowed to play with cards which lie on top of the deck/column.
Okay? I hope that answers your question.

Greetings to Italy
