This character confuses me...
For example my opponent has the Queen of Thorns in play (house of thorns); now, I know I can copy her triggered ability, but the question is: can I use it???
The queen of thorns says: "kneel the queen of thorns to cancel a triggered effect"... But I don't have the Queen of thorns.. So I can't kneel her (even if Dornan Martell has her triggered ability he is not the queen of thorns).
am I right?
