Even if this card is not directly targeted by the effects of the cards above, you can still activate this card's effect and do a lot of combos.
Destroy this card with "Scrapstorm", and use "Scrapstorm's" effect to send "Scrap Searcher" to the Graveyard to immediately replace this card with "Scrap Searcher". You can then proceed to send a different ScrapMonster card through "Scrap Shark's" effect.
If you need a beatstick, use "Scrap Lube" to revive this monster. It will negate Scrap Shark's self-destroying ability.
