"Sinister Serpent" Rating Score by 福人ズッコケ

"Treeborn Frog" returned to the hand.
Compatible with "King of the Feral Imps" and "Oshaleon" in terms of race, and "Where Arf Thou?" in terms of level. Also, with this card, 《Foolish Burial》, 《Genex Undine》and 《Snake Rain》are also converted from his GY to pseudo search. With [Mermail], the WATER cost is useful, and there are a wide variety of ways to use it, such as "Raigeki Break" for universal removal, "Abyss Soldier" for bounce, "Monster Reincarnation" for GY recovery, and "Karma Cut" and "Dark Core" for exclusion.
On the other hand, since the collection timing is limited, if you rely too much on this effect, there is a risk that you will not be able to raise the cost in time. If it's a hand cost, it can be fully rotated by hitting the standby phase repeatedly, but in many cases it is more effective to use removal cards such as "Sambre" and "Karma Cut" as well as permission cards during the opponent's turn. The familiar 《D. D. "Crow" and even "Rhapsody", which has excellent basic specs, appeared. It seems that his staying at GY has become more difficult than when he was active, and he is steadily walking the road to his return.
As an aside, the English name "sinister" seems to have the meaning of "evil" or "becoming a disaster". The Japanese name "killer" gives off a rather violent impression, like "killer" or "killer," but the word "killer" on this card has a more conceptual connotation. Maybe. This kind of expression has something in common with his own nature that he can steadily gain an advantage even with low status.
