Are there any monsters with Atk that’s equal to their defense that would go good with Sera’s Wave of Enlightenment skill. I only have one cubic monster with 1600/1600 and want to use the skill.
Slifer and Obelisk will always have ATK equal to their DEF unless they are changed by Equip Spells/Traps/Monster effects etc. Also Arcana Force have a lot of monsters with the same ATK as their DEF unless Emperor's effect (either one) is active,
yes there are monsters
Arcana Force is an archetype in which all the monsters have ATK equal to DEF.
Some big monsters of Ancient Gears also have ATK equal to DEF (Golem, Reactor Dragon,...).
