My Take on Competitive Spellbook

• Harpie's Feather Duster is Forbidden
• Thousand-Eyes Restrict is Forbidden
• 3 copies of Allure of Darkness, which is Limited (at most 1)
• 39 cards first released after Tengu's card pool closed (2011-09-17): Accesscode Talker, Apollousa, Bow of the Goddess, Artemis, the Magistus Moon Maiden, Beatrice, Lady of the Eternal, Bystial Druiswurm, Bystial Magnamhut, Bystial Saronir, Crowley, the First Propheseer, Dharc the Dark Charmer, Gloomy, Dogmatika Ecclesia, the Virtuous, Dogmatika Fleurdelis, the Knighted, Dogmatika Maximus, Dogmatika Punishment, El Shaddoll Apkallone, El Shaddoll Construct, El Shaddoll Winda, Elder Entity N'tss, Evenly Matched, Garura, Wings of Resonant Life, Ghost Reaper & Winter Cherries, Lightning Storm, Linkuriboh, Magicians' Souls, Millennium-Eyes Restrict, Nadir Servant, Relinquished Anima, Selene, Queen of the Master Magicians, Shaddoll Beast, Shaddoll Schism, Spellbook Magician of Prophecy, Spellbook of Fate, Spellbook of Judgment, Spellbook of Knowledge, Spellbook of Life, Spellbook of Secrets, Tearlaments Havnis, Titaniklad the Ash Dragon, Triple Tactics Talent, Wollow, Founder of the Drudge Dragons

Checked against the Tengu format Forbidden & Limited list (September 2011) as of 1 September 2011 and its card pool (no card first released after 17 September 2011), with the sizes and copy limits of a TCG deck.

Not checked: the TCG card pool (a card released only in the OCG).
