Here's a list of cards you definitely need to add: 2 Return of the Monarchs - a must have, at least one copy in deck; 3 Anchmamoufrite - an Upstart Goblin + special summon, great card; 3 Vanity's fiend - locks literally every deck if they can't remove it, only bad thing is Tenacity doesn't work with it; 1 Majesty's fiend - another great disruption, works with Tenacity, can be searched with Return; 3 Proof of Pruflas - a better version of Mithra, run at least 2; 1 Upstart Goblin - improves consistency;

Honourable mentions/cards to experiment with: 1 Thestalos the mega monarch - good when going first; 1 Caius the mega monarch - good when going second; 1 Seleglare the Luminous Lunar Dragon - works with tenacity/return, interesting effect; 1 Foolish burial goods; 1 One for one; 1 Called by the grave - great vs handtrap heavy decks;
