...Ancient World having his own TD? Okay, that's it, so you need a TD in order to play a World? I think not, just like you don't need a TD to start with a clan in Vanguard. Sure, it kinda helps having something to introduce you to that clan mechanics and it has some nice exclusives (Hi Daikaiser!). But it's not MANDATORY. And Ancient World DOESN'T have a Trial deck but a Extra booster along with Katana and Dragon worlds.

Extra Booster =/= Trial deck
