I like how Scrap Searcher works

Scrap Sorter
EARTH
Machine/Effect
2/500/500
When this card is destroyed by a "Scrap" card: Its effect is activated. While this card is in the Graveyard; if a Scrap monster is destroyed and sent to the Graveyard, you can add a "Scrap" monster with a lower Level from your Deck to your hand. (If the destroyed monster's Level is 1, you can add a Level 1 monster instead.)
