Countless, the Number of Memories

LIGHT/RANK 3/GEN/GEN: Psychic + Warrior/Xyz/Effect/ATK 2000/DEF 2500

2 Level 3 Psychic Monsters

Once per duel each, you can also Xyz Summon this card by tributing 1 Rank 3 or higher "Number" OR "Of Memories" Xyz monster you control. (Xyz Materials attached to a tributed monster become Xyz Materials on this card.) You cannot use the activated effects of other "Number" or "Of Memories" Xyz Monster cards the turn you activate this effect. (Quick Effect): You can detach 2 Xyz Materials (including 1 Xyz Monster card) from Xyz Monsters you control; 1 monster on the field loses 2500 ATK/2000 DEF (if not already currently affected by this effect) until the end of the any damage step it undergoes, but all damage any players receive from that battle is reduced by 2000.
