Goblin

Goblin is a series based on "Goblin Attack Force" and its variations. All members share the effect "If this card attacks, it is changed to Defense Position at the end of the Battle Phase, and its battle position cannot be changed until the End Phase of your next turn." (though not necessarily with the same wording), except for "Goblin Pothole Squad". They also share 0 DEF, with the exception of "Goblin Elite Attack Force" and "Goblin Pothole Squad".

Play Style
Goblins have an enormous advantage in ATK. Because of this advantage, Goblins may be the strongest level 4 monsters. However, though the Goblins have several advantages in their original ATK, they have a drawback that makes a deck containing them somewhat hard to use. This drawback is that after most Goblin monsters battle, they must change into face-up Defense Position. So, this Deck will be tricky to use in tournament play. To prevent this drawback, you can add copies of "Final Attack Orders". They will help you optimize the Goblins' strength. You can also use "Skill Drain" to prevent this effect while negating your opponent's card effects at the same time. You can also use "Zero Gravity" when most of your strong Goblins are in defense to switch them to attack, or for an added bonus use Gamushara. ("Zero Gravity" switches all monsters from their previous positions ex. defense to attack or attack to defense). These cards would also work well in a Spiders deck and Clown Control deck.
