many of this card is impossible to summoned unless you use RUM. Which for the longest time barring Utopic Zexal and the new PK Engine is not a viable strategy. That being said though some of the effects is really overpowered im worried that the ridiculous summon condition (also lack of immunity for some) doesn't even gonna tone it down depending on main deck support you will give in future. Coach hand wipe and Babel turn skip effect for example
