Vanquish Soul

This is a Vanquish Soul I've been working on. I think the monster lineup is perfect personally. The only problem is that I don't know what to replace the bystials with because I believe they won't impact the meta. Small World and Durendal are pretty much staples as they allow you to search your Razen. TCBOO is also a staple because the archetype can easily abuse this card. I think this deck runs consistently with 7-8 cards for each attribute (7-8 fire, 7-8 earth, and 7-8 dark). The extra deck doesn't really matter, but I do want to find better extra deck monsters to probably replace cards like Underworld Goddess and Bagooska as they really don't do anything and are barely summoned. Zoodiac package for Zeus. Security Dragon is meh, I would also like to find a replacement for this card (maybe a Tellar xyz package). The side deck is also in testing, but I think that Droll and Ogre are a must for the upcoming meta. Please leave any suggestions and techs. I would really like to test them out.

Edit: Added Heatsoul package.
The Heatsoul package is pretty good as it allows you to gain even more card advantage alongside having heavy borger. It does not take that much space, which is very good. (removed bystials and 1 panthera for parallel exceed, security dragon and underworld goddess for heatsoul and splash mage)

still looking for techs and other suggestions
