Not really, just use subs, like king of the swamps. But the problem is, this card is way too annoying to summon anyways, as you summon it, your opponent might just econ, floodgate, or destroy it... So, almost ENTIRE E-heroes are only N and R cards, except for stratos and a few more...
Not my favorite Elemental hero fusion but it would be good to have him and regarding how to summon him the easier way would be with miracle fusion, might come as clutch card but we need more support cards like stratos or E emergency call and many more and many more to improve elemental heros decks
It's hard to summon without miracle fusion and I don't have the skill so I think you can also use parallel world fusion by use different dimension gate and banish your fusion material and opponent's monster after that use parallel world fusion but your opponent's monster also shuffled back into the deck
being banished face down means a card is unindentifiable, but cards that talk about any and every banished card, such as this, still effect the face downs, simply because they don't card what kinda card it is
