Best card to use Inverse Universe is with cards like Big Shield Gardna. It has high defense and automatically switches to attack position when it's attacked, letting you activate the trap when he is targeted again.
Similarly to Big Shield Gardna, you can use cards that have high attack but low defense to trick your opponent into attacking them when they are switched to defense. Cards that automatically switches position can benefit from this.
- Monsters affected by "Inverse Universe" have their ATK and DEF switched for as long as they are face-up on the field.
- You can activate "Inverse Universe" during the Damage Step, but not during damage calculation.
- If the ATK of a monster is being changed by an Equip Spell and "Inverse Universe" is activated, the ATK and DEF switch, but the Equip Spell does not reapply its effect to the new ATK. When the Equip Spell is destroyed, the ATK and DEF of the monster do not change. New Equip Spells will modify the new ATK.
Feels like Floodgate Traphole but for different purpose or strategy!
