"Fossil Dyna Pachycephalo" Rating Score by みめっと

A great low-level monster that has been supporting his Deck for a long time since its appearance.
It's a monster with a rule-intervention type permanent effect that can be said to be a forbidden move that blocks all Special Summons, but like Christia, this monster itself is very good at being able to Special Summon, You can summon it with the Adamancipator tuner, chain it to the opponent's SS effect and revive it with Libide Back to the Front, or you can recruit it from your compatriots with a deck solidified with level 4 rocks.
In addition, the activation condition is slow when reversed, so it is just a comfort, but it has a removal effect that can be used even after it is effective against Special Summoned monsters. A mysterious card.
If you equip a moon mirror or phantom sword to support the hit point, or cover it with a big capture, mirafo, warning, etc., you will be strong even against low-level monsters that just summon and hit you.
Its stats are unreliable, but as a low-level system monster, I think it's the strongest monster that's on par with Inspe.
As a user, it's a monster like "Thank you for coming to Rock instead of Dinosaur".
