Master of Ham is an absolutely amazing card for any Flip Deck to have access to. For one, it is a Level 5 Fusion Monster which means that you can use Instant Fusion to get it out of the Extra Deck, and in doing so, you can Special Summon a Flip Monster from the Deck in face-down Defense Position. That could've been all that was written on the card, but it has another effect which allows you to banish 2 Flip Monsters from GY and/or face-up field to Special Summon it from GY in face-down Defense Position. And to make things even better, it's first effect to Summon a Flip Monster from Deck face-down activates on Fusion Summon or when it flips face-up which means that you can just do it again on a future turn. Master of Ham fixes one of the key issues within Prediction Princess which is your inability to easily access Prediction Princess Bibliomuse. Your previously most consistent options were World Legacy Monstrosity, Spirit of the Fall Wind, and Pot of Prosperity. If we utilize Predaplant Ophrys Scorpio and Predaplant Darlingtonia Cobra to search Instant Fusion from the Deck, we will be able to have access to Master of Ham getting Prediction Princess Bibliomuse from Deck while also giving you enough material on field to either end on an I:P Masquerena or even a 3 material Apollousa, Bow of the Goddess.
Main Deck: 3 Prediction Princess Tarotreith and 2 Prediction Princess Tarotrei. I will usually recommend playing 4 or 5 Prediction Princes Ritual Monsters, being a combination of some number of each. Tarotreith can be Ritual Summoned or Special Summoned via Tarotrei's End Phase effect. On flip, it can Special Summon a Flip Monster from Deck face-down and it can Quick Effect flip any number of your monsters either face-up or face-down. Imagine this card as Tarotrei who can flip multiple monsters at a time which means that you can definitely start with this card instead of Tarotrei and get access to Tarotrei later in your combo during your Turn to have her on field. Tarotrei can Quick Effect flip a monster either face-up or face-down and she can also Special Summon a Flip Monster from hand or GY in face-down Defense Position during the End Phase. 3 Prediction Princess Bibliomuse. Bibliomuse gives targeting and destruction protection to all of your Ritual Monsters. On flip, it searches a Prediction Princess monster and a Ritual Spell from your Deck to your hand, and if it is Tributed and sent to GY, you can Special Summon it back face-down. 2 Deus-X Krawler which negates the activated effects of all face-up monsters your opponent field after it has been flipped face-up and if it is destroyed, you can add a monster with a different type and attribute from it from your Deck to your hand. 1 Mardel, Generaider Boss of Light which searches a Generaider card or a Plant monster from your Deck to your hand on Summon. Mardel is here as a Level 9 target for World Legacy Monstrosity to target on field or to to Summon from Deck using it. 2 Lonefire Blossom which can Tribute a Plant to Summon a Plant from Deck. This basically acts as 2 extra copies of Ophrys Scorpio and it can also Summon Mardel from Deck which gives you a Level 9 target on field for Monstrosity. 3 Predaplant Ophrys Scorpio and 1 Predaplant Darlingtonia Cobra. Scorpio can send a monster from hand to GY on Normal or Special Summon to Special Summon a Predaplant monster from Deck. If Cobra is Special Summoned by the effect of a Predaplant monster, it can add a Poly or a Fusion Spell from Deck to hand. Scorpio Summons Cobra from Deck and Cobra searches Instant Fusion which gets you Master of Ham. But something that is even better is the fact that Scorpio and Cobra will remain on field. This gives you 2 material worth of Link Material or they can act as 2 Level 3 monsters for a Number 75: Bamboozling Gossip Shadow which can insulate you against a handtrap monster. 3 Diviner of the Herald which sends a Fairy from Deck or Extra Deck to the GY on Normal or Special Summon and gains Levels equal to the sent monster's Level. This sends Herald of the Arc Light from Extra Deck for a Ritual Monster or Ritual Spell search. And finally, 3 Ash Blossom & Joyous Spring.
Spell/Traps: 3 Underworld Ritual of Prediction which Ritual Summons a Prediction Princess from hand or GY face-up or face-down and you can also banish it during the Standby Phase to Special Summon a non-Ritual Prediction Princess from Deck face-down. 2 World Legacy Monstrosity which can Special Summon a Level 9 monster form hand or target a Level 9 monster on field and Special Summon 2 Level 9 monsters with a different type and attribute from Deck. This can get you material for a Rank 9 out onto the field for something like a Mereologic Aggregator if you still need to search for Ritual cards, but it can also get you Bibliomuse out onto the field and into rotation in case you did not have access to Master of Ham. 1 Instant Fusion which Special Summons a Level 5 or lower Fusion from Extra Deck which is treated as a Fusion Summon. This gets you Master of Ham which is what you really want in this Deck. 2 Triple Tactics Thrust and 2 Triple Tactics Talent. 3 Pot of Prosperity and 3 Infinite Impermanence.
Extra Deck: 1 Master of Ham which is just so good for reasons I've already stated. 2 Herald of the Arc Light which adds a Ritual Monster or Ritual Spell from Deck when it is sent to GY. 1 Divine Arsenal AA-ZEUS - Sky Thunder. 1 Infinitrack Earth Slicer which can detach any number of materials to destroy an equal number of cards on field and it can also attach any monster it destroys by battle to itself as Xyz Material which makes it great for board clearing and making Zeus. 1 Mereologic Aggregator which sends a monster from Extra Deck to GY on Xyz Summon which can be Herald for a Ritual Search and it can detach any number of materials to attach the same number of monsters from GY to it as material which can loop Herald for Ritual searches if needed. 1 Laevateinn, Generaider Boss of Shadows and 1 Jormungandr, Generaider Boss of Eternity as a Rank 9 you can go into for interruption. 1 Number 75: Bamboozling Gossip Shadow which can replace your opponent's activated monster effect with "each players draw a card" which can fade a monster handtrap for protection or you can also just use it as interruption also. 1 Mekk-Knight Crusadia Avramax. 1 Apollousa, Bow of the Goddess. 1 I:P Masquerena. 1 S:P Little Knight. 1 Sky Striker Ace - Camellia which can Summon itself to your opponent's field and send a monster your opponent controls to GY if it is sent to GY. You don't really need this card, but it turns Masquerena's Link Summon effect into a lot more interruption, and it is even generic. 1 Cross-Sheep which we are usually going to use either its Fusion or Ritual effect. If a monster is Special Summoned to a zone it points to, if it points to a Fusion, it can Summon back a Level 4 or lower monster from GY or draw 2 cards and discard 2 cards in the case of pointing to a Ritual. You can make this card with Scorpio and Cobra, Instant Fusion Master of Ham to a zone it points to, trigger Cross-Sheep to bring back either Scorpio or Cobra, giving you your Bibliomuse access as well as material for a 3 material Apollousa for 3 monster negates.
Side Deck: 2 Nibiru, the Primal Being. 3 Thunder King, the Lightningstrike Kaiju, 1 Triple Tactics Thrust, 2 Dark Ruler No More, 2 Lightning Storm, 1 Harpie's Feather Duster, 3 Evenly Matched, and 1 Dimensional Barrier.
