Wait, nevermind, you don't really need a Synchro Tuner, you can just summon a Tuner for the third Synchro.
Still, it's easier when one of the first two Synchros is a Tuner, since there are more self special summon non-tuners in the game than self special summon tuners.
Vrains is cool, however... I think Mr Kazuka takahashi should work again one more time at least :P just like they did with poor Toriyama lol (seriously... that guy never stops working lmao)
Vrains is the best sequel, at least for me. It has quite a mature story full of dilemmas about mankind, not that the rest of series lack the complexity Vrains has, but I dunno... it has something that makes it look more mature (despite the ignis guys lol)
Zexal maybe next year, if they decide to slow down since this is already almost half of the year and we still don't even see Savior Dragon stuff for 5Ds world, let alone the Accel Synchro stuff.
zexal and arcv will bring more money than 5ds did so yes we for sure getting them (with vrains is different they have to change the playing field for it and that "costs" alot)
