Rulings
- The effect of Lv Limit - Area B does not use the chain, it is a continuous effect.
- All Lv 4 or higher monsters face-up on the field after Lv Limit - Area B resolves will be in Defense Position. You can change the Battle Position of a Lv 4 or higher monster, but it will immediately be changed back to Defense Position because of Lv Limit - Area B's effect.
- If Lv Limit - Area B is activated while Final Attack Orders is applying, then the most recently resolved effect takes precedence and monsters Lv 4 or higher will be in Defense Position.
- If you Summon "Spell Canceller" while "Lv Limit - Area B" is on the field, "Spell Canceller" negates its effect and is not changed to Defense Position.
