This can look like picking just one artist, or even just one land from that single artist to give your deck a uniform look
Iron Hands looks like a rocket ship blasting into outer space, surrounded by vibrant colors
Pot of Duality is one of those big factors away from the more comboish elements of the deck, but the card selection it grants is amazing, and it works incredibly well alongside Extravagance, and most of the time you don't even want to special summon anything anyways
In addition, this combo can lead to a Summon of Isolde, Two Tales Of The Noble Knights to keep the combos going without worrying about Hand Traps
A number of actions also cant be cancelled once selected (but before being executed), making it easy to accidentally force yourself to sacrifice monsters because you misunderstood exactly what a card or effect required
Always start your combo with backrow removal spells like Lightning Storm or Harpie's Feather Duster if you have anything in hand to clear any possible threats on the field
