Beast-Type monsters are known for their high ATK values, and this makes them a good foundation for a Deck. "Berserk Gorilla" is a Level 4monster with 2000 ATK. There are few Level 4 monsters in the Yu-Gi-Oh! TRADING CARD GAME with an ATK this high, and most come with a high Life Pointcost, or strict restrictions on the way they are Summoned, making them unreliable. "Berserk Gorilla" does have 2 limiting effects. The first says that you must attack with "Berserk Gorilla" each turn. This is what you want to do anyway, unless they have a monster with higher ATK, but if you keep destroying their monsters, they will find it hard to Tribute Summon a big enough monster to stop the "Berserk Gorilla". The second effect of "Berserk Gorilla" is that it is destroyed if it is in face-upDefense Position, which means it can never protect your Life Points. This is only a small drawback, since he can destroy most monsters in battle when he attacks. This card is good in lots of Decks, not just Beast Decks.
