Megalith are a Rock-Type Ritual deck that was introduced into Duel Links in the Chronicle of Glory Mini-Box on July 13, 2020 (and around January 2020 in the TCG in Ignition Assault). It is by far our most advanced Ritual deck in Duel Links at the moment. They don't rely on Ritual Spells, and purely Ritual Summon using their monster effects, making Loading... an incredible searcher for the entire deck. The deck is capable of going first or second, and has a relatively good matchup against many different decks. Its main weakness is massive backrow removal from decks like Cyber Dragons and Blackwings, but it is inherently able to maindeck Loading... which is a great counter to Loading... .
Future archetype support could include Loading... , Loading... and/or Loading... , and of these, realistically we might get Aratron, possibly Phul, but for now, what we currently have is still competitively-viable, if not King-of-Games-viable.

KC GT June 2021 Stage 2 (Going-Second Strategies):
Here are the most recommended skills for playing the deck.
Master of Rites II
This is the strongest skill for the deck, purely because of so many people either not reading Loading... , or not having the sufficient removal to get rid of Ritual Cage AND your monsters in time.
This was the first skill used with this deck on-release, because it would more-easily enable summoning Loading... on the opponent's turn using only a Lv4 on your field without using anything in your hand. Nowadays this is not as recommended, but can be used if you don't somehow have Alexis Rhodes unlocked or Master of Rites II obtained yet.
