I'm more annoyed with its tiny hips, and the lack of Level-changing effect it has in the anime that would have made its Synchro Tuner status more usable.
The lack of Level-changing effect is even more puzzling as the anime version already has the effect since the start, as written in the text of the card in the anime.
This isn't like in the manga where Konami got trolled twice already, first with Elemental Hero Inferno and second with Stardust Spark Dragon, both have a new thing in the manga that wasn't present when they were printed in real life.
God you're dumb. Lifestream in the anime doesn't have that type of effect, Yusei used Speed Spell - Synchro Panic to summon the other 4 signer dragons and reduced their levels to 1 with it.
