Burgistoma
It is a deck based on Cambrian marine paleontology derived from the Burgess Shale Fossil Group of Burgess Shale.
Featuring the main trap excess, the trap card in the series is transformed from a special summon of the graveyard into a monster, which symbolizes the resurrection of these [ancient creature fossils].
Katu's prototypes are cambrian creatures found near the Burgess Shale.

Linjoli is a peculiar marine arthropod belonging to the great appendage family, extinct, mainly living in the precambrian period about 520 million years ago, also known as "primordial worms". Capable of swimming in the sea and crawling on the ocean floor, it is a four-eyed arthropod, and fossils are mainly found in places such as the Chengjiang Hat Tianshan Mountains in China and the Burgess Shale in Canada. The total length is about 3-5 cm, in the shape of a barrel cone, the front end is round, there are tentacles like a small whip, and the shape is very strange. The two whip-like organs at the front are thought to be able to hunt after whipping prey in shallow seas.
(1): It can only be launched against a monster represented on the side of the field.
The monster's attack power and defensive power increase by 500 until the end of the turn.
(2): When the trap card on the field is activated, the chain one can launch this effect before it can be launched from the graveyard.
This card becomes a normal monster (Aqua, Water, 2 Stars, Attack 1200/Shou 0) and is summoned in the monster area (not used as a trap card).
This card specially summoned by this effect is not affected by the effect of the monster, except when leaving the field.
The Obapien sea scorpion was an ancient animal of the Cambrian period. It lived in the ocean about 530 million years ago, probably in what Canada is now. They have 5 stalked eyes.
They look a lot like weird animals from science fiction movies, about 1.2 meters long. They use 14 pairs of paddle-like gills to swim. The strangest thing is their heads. The Obabine sea scorpion has 5 stalked eyes on its head and protrudes its trunk-like mouth, with a long soft mouth at the tip of these eyes and a claw at the tip of the mouth.
(1): It can only be launched against a card represented on the side of a table on the field.
Discard 1 hand card, except for the card that is the object.
Discovery of Marrella in Taijiang, China Abstract: Recently, important progress has been made in the study of the Kaili biota, and some important molecules of the Chengjiang biota and the Burgess shale biota have been discovered. The oddly shaped Marrella is an important arthropod fossil originally produced only in the early and mid-Cambrian Burgess shale biota in Columbia, Canada.
Also known as Pikaia or Pike fish, Pike worm. It is an extinct species of animal from the Cambrian Period whose fossils were found in the Burgess Shale of British Columbia, Canada. It was discovered by Charles Walcott and described in 1911. Because of the apparent and regular knots on the Pika fossil, Wolcott classified it in the order Polychaetes. It looks a lot like a cephalopod and may be more like an eel when swimming.
Oil-like ctenophores, also known as Kochsper's surprise, is believed to be the oldest member of arthropods.
Odd shrimp are 2-meter-long predators.
The grotesque worm is the most famous animal in the Cambrian Period, because when its fossils were first found, it was mistaken for the actual legs as decorations, and the hairs decorated on them were legs.
Fossils were found in the Burgess Shale in British Columbia, Canada.
