The rarity to never buy for spec: Secret Rares from non-competitive characters in recent sets
As the game goes on well keep Arixmethes at just one slumber counter and after a board wipe you can cast one spell, wake him up, and suit him up to start closing out games
If the opponent attacks this card while it's in a face-up attack position, they will have their own monster's ATK subtracted from their life points
If the target's in defense position as shown here, the enemy's defense value is used instead and the stakes change a little: in this situation, if the attacker loses, he takes LP damage but is not destroyed, and if the defender loses, the monster is lost but there is no LP damage
that damage becomes 0, also your opponent takes 1000 damage and you gain 1000 LP
