prinzessin yugioh deck Counter Fairy Trap - Parshath Ariadne Solemn Judgment Draco-utopian may be 1st or Unlimited Edition Yugioh Legendary Dragon Decks Yu-Gi-Oh!

On the one hand, the lack of abilities other than ATK makes this dinosaur a fairly unremarkable card

Kaalia of the Vast can cheat it from your hand (since it's a dragon), Yuna, Hope of Spira can bring it back from your graveyard (since it's an enchantment), and Esper Terra can copy it and trigger most of Bahamut's value by advancing three chapters: Summon: Bahamut isnt legendary, so Esper Terra has no problem copying it

If an ability words ability refers to an ability that can be triggered by an ability on the same card, as long as the wording of the card allows it to be triggered by itself, this is fine

If their definition of "best" is the strongest and most meta cards, they are likely a competitor
