"Forest" (森（もり） Mori) is an archetype mostly consisting of Beast monsters used by Luna in the Yu-Gi-Oh! 5D's manga. They have various effects relying on Field Spell Cards, to which Luna uses together with the "Fairy Tale" archetype and her "Ancient Pixie Dragon" to trigger their effects and create deadly combos. Few of them instead have effects which allow Special Summons, which makes "Ancient Pixie Dragon" easier to Summon.
