This would probably be be best represented by destroying/banishing it, although a simple attack loss, or an inability to attack might be enough
Meaning if you roll even slightly above average, you have the potential to destroy every (face-up) monster on the field
Its very rare that we see cards like this printed, so I wouldnt be surprised at all to see Boltwave show up in Burn decks in every format
However, this card is also great to use as link material, as it can special summon a level 3 or lower Geargia monster when it leaves the field, making this card able to extend combos in different ways depending on the board state and what handtraps the opponent used
Or my Faldorn, Dread Wolf Herald deck
While Daretti, Scrap Savants final ability wont necessarily end the game for you, it effectively freezes your board state as far as artifacts are concerned even if you dont have your winning combo on the board yet, its safe to say youll have all the time you need to assemble it
