Yes! another Eldlich deck, on the other hand, it is competitive blended with the Matchmech archetypes. There you can synchro summon one particular boss powered monster. With interesting support cards also, recommend this deck due to how fun it is to use!

Geomathmech Final Sigma is unaffected by all card effects except Mathmech cards. Battle damage is doubled if this card is in the extra zone. And lacking in attack, when it can be destroyed by battle, you get a card from your deck. Mathmech Multiplication is key to summoning the level twelve and one other Mathmech on the field which will be usually special summoned.
Mathmech Superfactorial can get the 3 XYZ monster from the extra deck capable of multiple effects.
Golden Lord is both offensive and a draw engine explained in my previous decks and combos > https://ungroovygords.com/2020/07/28/yu-gi-oh-deck-and-combos-eldlich-the-golden-lord-invoker-hybrid-2020-update/ – These are your second boss monsters that should be consistently summoned and power up with Moon Mirror Shield or Power of the Guardian. Zombie Necronize helps to summon, discard or while summoned depending on timing.
Ash blossom, Immortal Pheonix Gearfried, Starlight Road, Golden LAnd Forever, Linkuriboh, Dark Sanctuary and Mystic Mine continue the rest of your stalling protection.
Side Deck > Witch’s Stike, Pot of Desires, whatever else
