"Heavy Metal Raiders" Rating Score by とき

Keith Monster All Stars. …To be honest, these cards are hard to comment on.
The effect is to give his Machine / DARK monster a one-time battle destruction resistance and increase his ATK by the amount of damage received, and once per turn, the Machine / DARK monster will be destroyed by battle or by its own effect. An effect that allows you to Special Summon his Machine/DARK monsters from your hand when you destroy a card.
However, it is difficult to aim to activate the first effect unless it is a suicide attack. It would be enough to restrain the opponent's attack. There are a lot of powerful cards in Machine/DARK monsters, so it might be worth adding resistance to them.
The second effect is the main line, and you can aim for revolvers and blowbacks from the removal effect of light monsters such as Bomb Spider and Twin Barrel. However, he can only Special Summon cards from his hand, and since he can only Special Summon once per turn, he will not be able to do it in a chain reaction with the effect of the monster he Special Summons.
Overall, I feel that the power is suppressed. Was it difficult to talk about it because it was tied up with racial attributes?
