"This has been discussed several times in this forum. Because OCG rulings are not official in the TCG, there are no TCG rulings for Xyz Summons at all and in the interest of maintaining consistency with an official source, the well-seasoned judges (aka those judges that are typically Team Leads and HJs at the Premier Events in the U.S.) are currently ruling that if Reborn Tengu is used as Xyz Material, the effect of Reborn Tengu will still activate.
This is not because we disagree or agree with the OCG rulings on Xyz Summons, contrary to what some may think - this is because judges in TCG territories should rule, ultimately, in the perspective of the TCG, not the OCG. In that vein, we then rule in that perspective to maintain consistency in our events, at least, until the article is either clarified or else official rulings are passed down from R&D regarding Xyz Summon mechanics."
Also vorerst wollen die U.S. Judges Tengu so rulen, dass ein neuer aus dem Deck kommt wenn er für eine Xyz Summon benutzt wird.
Eine offizielle Bestätigung wirds wahrscheinlich erst ab dem neuem Structure Deck geben.
