You can return 1 Firewall and 1 Decode Link-3 or higher Monster to the Extra Deck (1 from your field and 1 from your field or GY): Special Summon this card (from your Extra Deck), and if you do, you can negate the effects of up to to 4 cards on the field, and if you do that, this card gains 500 ATK for each card negated
This ensures your cards are always within reach, eliminating the need to fumble around in a bulky traditional wallet
Players an Instant Win Last Turn is a trap card that triggers an instant win effect
By the time he hits the field, you should have plenty of Gem-Knights in the Graveyard to boost his ATK, and if you need an effect from a Gem-Knight that's already defeated, he can banish it from the Graveyard to copy their effects while maintaining his own ATK and DEF
