Hola. Compré un sobre y tengo duda con carta CEREBRO - Cibernetic Intelligence. N62- place Cerebro on an X-men die's card. It remains there until you or a card effect removes it (it is still in the field). When you field a die from that card, knock out one opposing die.

A que se refiere con X-men die's card?....como funciona esta carta?.
Saludos y feliz 2015!!
