Don't let anyone say the Utopia equip monsters cannot be targeted through breakthrough skill.
They are equipped yes, but are still considered a face up effect monster.
I've had to deal with a lot of players saying they can get away with it.
For instance, he had his utopia try to run over my scrap dragon, and with the ZW- Tornado Bringer, it boosts utopia with 1300 atk, making him 3800, leaving a 1000 atk over my scrap dragon. I chained breakthrough skill on the equip and he raged out.
