So, update on yu-gi-oh: no, kashtira is around, but I wouldn't say it was doing anything nearly as heinous as it used to, cards got limited and are occasionally used as an engine for stronger decks. Currently a rank four strategy in ryzeal and a link banish deck, Maliss are tearing it up, though some new competitors are stepping into the scene, challenging their utter dominance. Hand traps at every corner though, so really it's more of the same, just generally more interactive.
