Rulings
(1) If there are no face-up Insect-Type monsters (except this monster) on your side of the field, both the ATK and DEF of this monster become 1000 points.
- The (1) Continuous Effect applies while this card is face-up on the field.
- If you have 2 Arsenal Bugs on your side of the field, each has ATK 2000.
- If the only other Insect-Type monster you control is face-down, the ATK of Arsenal Bug is 1000.
- If the ATK of Arsenal Bug is 1000, and it is equipped with an Equip Spell Card or modified by a Field Spell Card, recalculate. So begin with the 1000 ATK, then increase or decrease from there according to other card effects.
- When Arsenal Bug is Summoned and there are no other Insect-Type monsters on your side of the field, Bottomless Trap Hole can't activate because its ATK is 1000 when Summoned.
- If you equip Megamorph to Arsenal Bug then its ATK will be 4000 or 1000, depending on Megamorph’s effect.
