Did anyone notice the trait states "Gate Guardian" on it? Shouldn't be replaced with its own name? Or is it literally like that on the card?

Yeah, the card says Thousand Dragon in the instances that Gate Guardian is being used. My guess is copy paste with changes made to the fusion materials.

As long as this thing gets the ruling to make its fusion usable (because DUH) I am going to enjoy using that flame breath power to flambe conga lines. Or just popping suckers straight up with PPB. Either way you choose to use, great ranged figure for 175 and a great Fusion, only real weakness (if you can call it that) is mediocre movement dropping to low movement.

Interesting to see a Fusion monster that really doesn't want to be dropped in on its first click-- the second click is better in every regard, getting that crucial Running Shot. Since neither of the fusion-material monsters for this old guy have Indomitable, I'm calling that good design!
