Lvl: 40 Gate Guardian Farm
- Special Summon Gate Guardian.
- Attack face-down Monsters whenever you can.
- Don't attack face-up Monsters if he has backrow! - Tristan has Battleguard Howling which inflict Burn Damage if your monster attacks his Warriors.
- Use your draw cards to finish the duel quicker.
- Note: Don't use Cards from the Sky if you'll end up with 0 cards in deck after the effect since you won't be able to conduct your Battle Phase.
- Summon Gravekeeper's Vassal.
- Target Vassal with your three Union Attack and Secret Pass to the Treasures.
- Enter the battle phase and attack directly for victory!
- You can replace one Union Attack with Axe of Despair, Battleguard Rage, Blustering Winds, Back-Up Rider, Caligo Claw Crow etc.
- Winged Kuriboh + The Flute of Summoning Kuriboh + Cards from the Sky combo can be replaced for Gravekeeper's Recruiter + Wonder Wand and 3 other draw cards or Normal Monsters + White Elephant's Gift.
- Shard of Greed can be replaced by other draw cards (filter by "Drawing" in the Card Editor) such as Good Goblin Housekeeping, Legacy of Yata-Garasu, Jar of Greed etc.
Lvl 40: Skill-less Yubel Farm
- Generic Skills you can run are Draw Sense: High-Level or Restart
- Use Sangan to search for either Planet Pathfinder (To search for Fire King Island) and/or Yubel
- Using the effect of Fire King Island or Fire King Avatar Yaksha, Destroy Yubel in your hand, using the card's effects to search Fire King Avatar Yaksha and summon Yubel - Terror Incarnate from the deck
- Once Terror Incarnate is out, keep drawing through your deck by using Sangan, Planet Pathfinder, and Fire King Island.
Note: Make sure to keep at least three Monsters (Ideally high Level Monsters) in your hand for Montage Dragon.
- Special Summon Montage Dragon in Attack Position by discarding three (ideally high Level) monsters
- Normal Summon Gravekeeper's Vassal and use both Union Attack and Secret Pass to the Treasures on it.
- Attack Directly with Vassal
- Montage Dragon (and a Planet Pathfinder) can be replaced with The Calculator and either Photon Lead or Double Summon
- Sangan can be replaced with additional Planet Pathfinder or any suitable Draw card. I would reccomend Crystal Seer to help you dig for the pieces you need early or Vortex Trooper as it will draw you cards both before and after Yubel is on the Field.
