When Tristan reappears at your house, defeat him again
I would like to show you one of the decks that I call ~Monarch mathematically unbrickable
When investing in Pokemon cards, or any other collectible, you want to make sure to purchase a piece that has a (very) low number of copies in existence
Instead, always prioritize lower-cost cards that trigger desired effects off of the rest of your deck, as this is what will ultimately gain you control of the board
It also synergizes well with Muna Hero Rin & Orchid, where you're looking to advance in Forest expeditions to gain card advantage
Must be either Fusion Summoned, or Special Summoned (from your Extra Deck) during the turn a Spell Card or effect is activated, by banishing 1 Level 6 or higher DARK Spellcaster monster you control as material
