Not quite. Cards are key legal if they have the symbol in the lower-right corner of the card, or if they're a level 0 LRIG. This includes most cards printed in and after Klaxon, but not all of them.

Besides, the group of sets with key symbols on them is completely consistent. It includes all WXK-P sets, WXK-D decks, Tawil key and Fitru, and promo cards with "K" in their set numbers. This card doens't break any previously established rules.
