Bayushi Hisoka enters play, targeting a ring. My opponent is playing Mountain Summit Temple and bows his Monk to put the Ring back into his hand. What happens when that Ring re-enters play? Does it remember that Hisoka targeted it?
Mountain Summit Temple Text Limited: Bow one of your target Monk Personalities: Put one of your Rings from your hand into play, from play into your hand, or from your discard pile into your hand.
Bayushi Hisoka After Hisoka enters play: Target a card. While Hisoka remains in play, after each time that card bows, its controller loses 2 Honor.
Thanks!
