I run 3 Raiden/1 Minerva right now on DevPro.
i want to see your build
If it ever gets made into a synchro, I think it can have some accessibility because deck builders are creative, and sometimes they can justify the slot. Yes this game can be said to be creative. However, a lot of cards like these confuse people such as myself who already see builds of these in the internet. These card choices, might be considered serious in a plant deck maybe. However, it's not bad. It's generic removal if you have the excess life. Or 1000 lifepoints to pay for it.
i mean yeah if its a generic synchro itll see play in anything that makes synchros, its effect is good enough to warrant a spot in almost any deck, im just not convinced it will be made into a generic synchro (nor should it be)
1 tuner + 1 or more non-tuner ls monsters would make the most sense to me
