Usually, if a monster equipped with an Equip Spell Card is destroyed, returned to your hand, shuffled into your Deck, sent to the Graveyard, turned into an Equip Spell Card (by "Relinquished"), flipped face-down, or anything else so that it is no longer a face-up Monster Card on the field, all Equip Spell Cards equipped to it are destroyed
Those that arent are more mechanically unique, and will generally see play as metagame calls or in specific decks, if at all
Just place your case and display
Trying to KO the Garbodor is also a great strategy, as it will hopefully allow for extra turns of Abilities, while avoiding the dreaded Sledge Hammer turn by taking 1 Prize, and then 2 more on a Buzzwole- GX
