Had a Arena fight against a fellow with Lion Prince in his deck. Read his skill info, destroy a row blah blah. Not a treath. WRONG --> prince wiped the whole screen, checked the description multiple times (A row, thats 1 right?).
So yea, at least in this case, the card kept spamming his skill, gaining extra turns occasionally and instarefreshing since the whole table was cleared each time. Wasnt too fun.
