yugioh crashbug deck Bugman Xyz 2012 / DARK Crashbug Road - Yu-Gi-Oh! Card

This is particularly effective with Jared Carthalion, since he can target himself with his -3 ability

Negating the cards that could potentially get rid of it makes it all the harder

This means that if you target your own permanent with it, you can simply choose to copy the Chain as many times as you want at least, until you run out of noncreature permanents to target

This is one of very few cards on this list that isn't graded PSA 10 - and since a copy has never been sold in PSA 10 condition, it's hard to know if they exist at all

The only real scenarios I see this card being used is when you don't need it

It also decreases the attack and defense of all Pyro and Machine monsters by 200
