Reveal 3 Warrior-Type monsters from your Deck, including at least 1 "Black Luster Soldier" monster or "Gaia The Fierce Knight" monster, and have your opponent randomly pick 1. If they picked a "Black Luster Soldier" monster or "Gaia The Fierce Knight" monster, add it to your hand and send the rest to the Graveyard. Otherwise, send them all to the Graveyard. You can only activate 1 "Beginning of Heaven and Earth" per turn.
Apparently it can be assumed that Gaia represents Earth while BLS represents heaven. I think it's clear that there is a card called BLS - Envoy of the Beginning. Also since most BLS monster utilize their effect by having cards in the gy, it can be said that this card might be the beggining of powerful destruction about to come by sending more monster from deck to gy
So how exactly are u supposed to run this card. I assume u can show the opponent 3 BLS then send 2 of them to the graveyard and then just super soldier synthesis them out. Is it basically just a deck thinner.
Ideally you only run 1. Useful if you brick first hand but have it. Show bls, twilight knight and beginning knight. If they guess right, you get bls if not they're both in the grave. Special summon a bls variant (banish the 2 knights in grave) and you get to add both bls ritual and bls to your hand from the deck.
