the spell power bond lets him fuse his monster + gives him attack, to its original attack. but the monster would be destroyed at the end of the turn. thats the downside of that card, but it doesnt take place, when you cant defend the double 5k attack :D
This card will be in a Cyber Dragon Structure Deck EX - I guarantee it!
It's too easy to summon. You can easily get 2 of them onto the field with Cyber Style and it can attack your opponents life points. Not like Chimeratech that only allows you to do multiple attacks on monsters.
