Hi everyone, quick step on how to win your duels
Normal summon Serziel --> Search for Basilius or Catoblepas (the one you don't have in your hand) --> Special summon Basilius and send Eye of Gorgon to the graveyard --> Banish Eye of Gorgon to discard Catoblepas and search for Eye of Selene --> Equip Selene to Serziel --> Special summon Catoblepas and protect Eye of Selene --> Link summon Union Carrier using Catoblepas and Basilius, then use it's effect on Serziel --> Your board is good and you only use 4 summon no Nibiru.
(Notes : keep Evil Eye repose in main deck , it's too damn good. + If your opponent likes Kaiju too much, then side Metavers and Zombie world. + Po of extravagence might seems scary but in the end it almost never banishes all your Gorgon and/or Union carrier so please do use it)
