Another of Joey's cards from his regular Season 5 Duel with Mai Valentine. Here's the effect: ""Baby Dragon" + "Jinzo" This card can only be Special Summoned by removing from play the above cards you control. (You do not use "Polymerization".) Halve the ATK of all monsters your opponent controls and the ones they Summon. While this card is face up on the field, negate all Trap Cards on the field and the ones that are activated."
