Grand Revolution!
Counter Trap Card
Activate only if you and your opponent both control XYZ monsters. Special Summon their XYZ Materials in Attack Mode, and underlay the other player's XYZ Materials to you and your opponent's respective XYZ monsters. If the Materials do not fit the Material requirements listed on the XYZ monster, return the XYZ monster to the Extra Deck, and return the monsters to each player's respective hand. If the Materials fit the requirements listed on the XYZ Monster, that monster remains on the field.
