Lvl 40: Silent Magician Farm
- NOTE: This Deck doesn't have an answer if Kalin both goes First and Activates Mausoleum of the Emperor. The likelihood of this happening is low.
- Summon Silent Magician ASAP using Silent Magician LV4 or Spellbook Magician of Prophecy
- Search Silent Magician and/or Silent Magician LV4 by discarding Silent Burning with Transcendent Crystals
- Negate any problematic spells like Mausoleum of the Emperor and Infernity Launcher
- Attack Kalin's monsters to avoid Hundred Eyes Dragon plays
- Get a second Silent Magician up before Last Turn
Lvl 40: Cloudian Farm
- Get a Cloudian with Spirit Barrier or Intrigue Shield on the field ASAP. (Ideally Spirit Barrier ASAP because he has direct attackers)
- Have a backup Cloudian in your hand just in case he uses ZERO-MAX
- Use Pot of Benevolence to counteract his mill (the later the better - ideally you want to send back his Spell cards)
