Using the clown monsters and rabbits, their effects will allow you to either destroy their monsters or return them to their hand. This works quite well against Pegasus since Toon monsters can't attack the turn they are summoned.
Since the aim of this deck is to get a high score, you will perform a fusion summon, Ritual Summon and also use Summoner of Illusions to get Blue Eyes Ultimate to reach over 5,000 damage.
It's recommended to do this gradually as you progress in your turns since you will most likely not be able to do them all in the same turn. Start by summoning Dream Clown and/or Blade Rabbit and have them in a different position each turn while also turning them every turn manually if you don't have Labyrinth up. Slowly start to either fuse or ritual summon in a way where you still have monsters on your field that can take care of enemy's monster, but try to leave 1 monster slot open for the last turn so that you can set a Summoner of Illusions and then use Desert Sunlight.
Don't turn off the notification
If you happen to be using "Toggle Button" for the Activation Confirmation, make sure to not turn the notification to off after you set your traps like Curse of Anubis, Windstorm or Desert Sunlight. This is because Pegasus's Copycat and Big-Tusked Mammoth can attack the turn they are summoned. If you only have a copy of Blade Rabbit or any of the clown monsters and it gets destroyed, then it will be difficult to manage the earlier turns.
Obtaining a high score
There are a few things to keep in mind when trying to get a high score:
Perform ritual, special and fusion summon for the bonuses.
Try not to get hit for the no damage taken bonus which is 500.
If you get hit, that is still fine. Avoid inflicting battle damage to Pegasus's LP until you finish a duel, then you can get "Comeback Victory" assessment.
Other notable stuff
While skills aren't necessary, it can help you handle the earlier turns if you use skills like Bandit Keith's Switcheroo, Tea's Duel Stanby!, or Restart.
Blue Eyes Ultimate's purpose is to easily deal over 5,000 damage with 1 Riryoku, but you can use other high attack monsters and use 2 Riryoku if you don't have it.
You can put in a high level monster to get a tribute summon bonus.
Use a Xing Zhen Zu to prevent him from using any traps at all once he sets two and let him keep toon world. You dont need Ryoku if you are using GotM since it takes the entire attack of BEUD. If his copy is getting you, infinite dismissal works well as does Skull Lair.
You give piranha army Secret passage to the treasures and half of blue eyed white dragons atk with Riryoku.
After that you use Gift of the Martyr to destroy Blue Eyed White Dragon to give Piranha Army another 3000. After that the piranhas will have 5300 atk.
If you now attack the lifepoints directly piranhas effect will double the damage it does
I have won 3 out of 10 duels against lvl 40 pegasus using this exact same deck, no mistakes made. Gets a lot of points if you win, but not very consistent
This stupid deck has screwed me a number of times going against just level 30 Pegasus. On the last turn he uses his golden apple card to score a monster with the same attack/defense of my monster. And/or uses his trap magical arm, and when trying to flip summoner it causes my other cards to be in defense position which makes it so I can't attack any more and then I end up deck out defeat. I have yet to be able to summon any monsters from my fusion deck.
Each farming deck is tailored to a specific LD of a specific level. A Pegasus lvl 40 farm deck will work far better against Pegasus lvl 40 than lvl 30. Similarly a lvl 30 farm deck will work way better against Pegasus lvl 30 than a lvl 40 farm deck.
I failed using this deck when Michizure destroyed my Clown, Pegasus copied it and later on also destroyed LoN, 40 starchips wasted...What am I doing wrong?
