booster box size pokemon 151 (Japanese) With flat surfaces and sleek Pokemon Small Booster Box Protectors

While you control a Link-3 or higher "@Ignister" monster in the Extra Monster Zone, when an opponent's monster declares an attack: Special Summon from your Extra Deck any number of non-Link Cyberse monster(s) with 2300 ATK, whose combined ATK is less than or equal to the attacking monster's ATK, then end the Battle Phase

As Slifer gains 1000 ATK and DEF for each card in your hand, this move will probably change the tide of the game in your favour: not only it would probably make the Sky Dragon a strong monster but you should probably be able to score a substantial direct hit to your opponents lifepoints as all their monsters have been wiped out by the magic card
