Medusa Worm
(EARTH/Rock/2/500/600)
You can flip this card into face-down Defense Position once per turn during your Main Phase. When this card is Flip Summoned successfully, destroy 1 monster on your opponent's side of the field.
Welcome to today's CotD, Medusa Worm.
Medusa Worm is one of the many new rock-type monsters introduced in TLM. Much like its companions, and many other monsters, Medusa Worm has the ability to flip itself face-down, and then when it is flip summoned, an effect is triggered. For the Worm, it's monster destruction.
This can be abused in several ways in a rock themed deck. First of all, there's Hieracosphinx, who will prevent your opponent from attacking your face-down monsters. This will let you use Medusa Worm just about every one of your turns, unless your opponent uses something like Ceasefire or The Spell Absorbing Life. But I think I like a much more shrewd way of doing things with Medusa Worm. All you need is a Level Limit - Area B and another Worm. You should usually be able to destroy two of your opponent's monsters per turn with this, as Medusa Worm is really better off in doubles. The Level Limit will ensure its safety in case Hieracosphinx is not around. You can then attack your opponent with other rocks like Giant Soldier of Stone, who will be reviewed later this week.
Another card that goes well with Medusa Worm is Shifting Shadows. As long as you have another monster that can flip face-down, you've got a solid strategy. I recommend Moai Interceptor Cannons, as it has a DEF of 2000 and can flip face-down. By using Shifting Shadows, your opponent can't know where the worm went, thus they may attack the other monster, or monsters, instead. Very nasty right there. After a while, you can reduce your opponent's field to nothingness.
However, Medusa Worm is not a card you can just throw in anywhere and expect it to part seas for you, no no. This card requires a theme built with it, preferably rocks.
Rating:
Advanced Rock Deck: 3/5. Pretty good monster removal with all of the support rocks have to protect face-downs.
Traditional Rock Deck: 2/5. Chances of it staying for a while are slim.
Sealed: Whuped ass/5. See chaosruler's post.
Limited: Hmm..../5. See above.
Art: 1/5. It just... makes me want to... **pukes** yeah, that...
