Sorry, but that is a legal move. The check for a "Jackknife" card in the drop happens after the cost is paid, not before. Dragon Knight, Hijikata has a similar ruling where if the gauge you pay is Wolf of Mibu and you had none in the drop beforehand, then it's a legal move to do it and add that card to your hand. Just be sure that your opponent knows that if there is no Jackknife card in the drop or a Ritter on the field, even after the cost is paid, then the effect fizzles and they paid all that for nothing.
