yu gi oh dark world structure deck Yu-Gi-Oh! TCG: – Toy Mandala This new form of Reign 🐨 Structure Deck: Dark World

It has basically just gone up in price from there

Besides the Ability, Crawdaunt just has one move called Crabhammer, this move requires three energy cards to use, two colorless and one darkness, and does 60 damage

And even if the Lessons deck specifically wouldn't take the crown, there was also Izzet Looting to further homogenise the colour pie

You can only use this effect of "World Legacy - "World Crown"" once per turn

With Iono out of the format, the only means players had of interfering with their opponent's hand was the card Unfair Stamp, which is an ACE SPEC card and thus capped at only a single copy per deck
