[TIP] MAKE A BURN DECK, PART 3 Since a Burn Deck utilizes many Effect Monsters to deal Effect Damage, you will need a way to protect them from your opponent's attacks. The Continuous Spell Card, "Level Limit - Area B" can do this for you. Its effect changes all face-up Level 4 and higher monsters on the field to Defense Position. This prevents the opponent from being able to attack with his strong monsters.
"Level Limit - Area B" is not a perfect defense, as Level 3 monsters may still attack you. Most have low ATK, but you should be prepared for surprises.
