Thunder X Shredder

■ You may only cast this card if you have a 《Thunder Empire》 on your field.

■ Put the top card of your deck into your gauge, choose a 《Thunder Empire》 on your field, and for this turn, give it power+1000 and Penetrate. Then, if you have 4 life or less, for this turn, the chosen card's attack cannot be nullified if it is attacking alone.
