SE Secret Rare Mirror Force X TRAP When an opponent's monster declares an attack: Destroy all your opponent's Attack Position monsters

If you are missing too many lands or cards that interact with suspend cards it is a good idea to mulligan

Use this new monster to Summon one of the higher-level Red Dragon Archfiend Synchro Monsters and you can Special Summon the original Red Dragon Archfiend from your Extra Deck AND eliminate all your opponent's Attack Position monsters without needing to battle

Also helps secure game by breaking through monster walls

At the end of the day Maxx C is a deterrent to make the opponent think twice about summoning from the extra deck and potentially screwing you over by doing so
