Able to inflict considerable damage to opponent’s Life Points.
Cons
It is a limited edition card, you cannot farm for it.
You lose a strong monster in the process.
The trade off between your monster’s ATK and the inflicted damage (half your monster’s original ATK) isn’t that good.
Tips, Related Cards, Rulings
This card is only useful if you are able to constantly maintain field presence with Ancient Gear monsters. Also useful if you are running a burn deck variant.
Other than that, it is realistically not useful and not worth it to trade your strong monster for half of its ATK damage to your opponents.
You need to sacrifice 1 of your Ancient Gear monsters to use this card.
