First there are several combos with this deck but you need to know the basics.
All the trap cards (except karma cut) are meant to be destroyed by Serziels effect or another and the true best field is Link 4 Abomination and Serziel equipped with either evil eye equip spell (use Gorgone is Life Points are lower than opponent) with a few xyz monsters just in case.
Combo 1: Evil eye domain/Serziel + Any unchained Spell/Trap= Use domain to get Serziel, Summon her and search for Evil Eye Selene( if lp lower than opponent use Gorgone) and equip. Set unchained Spell/Trap and if opponent has special summoned monster destroy. During standby phase destroy set spell/trap and summon Unchained soul to the field----Easy 3k damage monster that can destroy any card on field(effect) and way to destroy special summons.
Combo 2: Tour guide = One card combo here, summon tour guide and now you have a choice, either summon Basilius, link summon Gorgon and equip Evil Eye spell/ summon Basilius the same but xyz summon to get pure power 3k damage dealier/ or summon any unchained monster and link summon Soul of rage and next turn use opponents monster to link summon Soul of Anguish.
The extra link and xyz monsters add extra versatility in case you need to switch up and good hands to draw. Feel free to add you own twists to the deck, if you want to cheapen the cost the knightmare cards aren't needed and you can sub karma cut for any hand trap you feel is good.
Hope you make strives with this deck, from Creator
