Notes & Combos
The Mekk Knight engine offers searching, some protection and a decent Link-3, but they can be harder to summon. Feel free to replace it with more Alpha, Big Foot or Gizmek Orochi.
Lava Golem conflicts with Fairy Tail Luna, so they can be replaced with Sphere Mode or more Gameciel. If you do so remove Owner's Seal.
Summoning Dingirsu then making a 4 or 5 material Zeus should be your safest play. Final Sigma and BLS are also decent choices, while Draglubion offers OTK potential.
