lightning card sleeves Dragon Shield - Dual Matte fitting Standard Dragon Shield Sleeves Case Dragon

Honorable Mention: Ashes to Ashes and Oubliette Two pretty unusual removals for Black are Ashes to Ashes and Oubliette

On average, I have six of every card

If you have one or fewer security cards when played, Omekamon can immediately digivolve into Omnimon X, and since Omekamon counts as the named card X Antibody, Omnimon X will trigger the board wipe in addition to the bottom deck ability

The Blue cost instant will dig four like Impulse, draw one and then bin the rest

(You do not use "Polymerization".) This card gains 400 ATK for each Spell/Trap Card on the field

This will offer you a 3000 attack monster with a number of materials that can be used to send all other cards on the field to the graveyard
