Energy Layer - Xcalibur

As you can see Xcalibur is a Attack type bey as being the the first version of it isn't as powerful as the other three but it dose pack a punch with its sword that is where all the beys attack goes but it power is also its greatest weakness so against a strong defense type it will burst

Overall
Sure the beys attack is decent for its generation but its very light and it has higher changes of bursting because of how much power it uses against its self so basically good for its own generation.
