Today's card is Scrap Worm. The worm is a 2-star earth insect tuner with negligible stats. Its effect allows it to attack directly, however, it is destroyed at the end of the battle phase if it does. Also, if it is destroyed by the effect of a Scrap and sent to the grave, you can add a Scrap other than Worm from your grave to hand. And FYI, if he is destroyed by his own ability, the effect still goes off. So you summon him, peg your opponent for 500 direct, then get to pull a Scrap from grave to hand. And if you need, he's a 2-star tuner as well. I'm not too terribly familiar with the Scraps, but this seems pretty useful. At least, there's no obvious downsides I can see.

Scrap Worm, another bit of support for the Scrap theme, though this time its pretty lackluster. Being a level 2 EARTH Insect doesn't do much to help within its deck, and Scrap Worm can't be effectively used in other decks either. It is a tuner though. It can attack directly, and if it attacks, it is destroyed at the end of the Battle Phase. When destroyed by a Scrap card (including its own effect) it returns any Scrap monster other than Scrap Worm from your graveyard to your hand.

It has the benefit of destroying itself easily, allowing you to grab what you want right away. The problem is that usually you want to grab those cards before the Battle Phase, not after. Scrap Worm also likely used up your Normal Summon, meaning it's very hard to take advantage of it. At least a direct attacker is something new to the theme, allowing them to poke for little bits here and there when there are defenders in the way. It useful when combined with Scrap Golem to keep reusing it.

Overall you're probably better off using Scrap Breaker and Scrapstorm to destroy other Scraps, rather than using Scrap Worm on itself. A copy or two might still be useful in some builds, as it has its niche uses and is a tuner.
