The Deck Builder's Toolkit (Amonkhet Edition) is a box set that was released on April 28, 2017. It contains 100 basic land cards (20 of each type from Amonkhet), 85 fixed cards, 40 of 125 semi-randomized cards suitable for building several different Magic decks, and four 15-card booster packs, two from Kaladesh block and two from Amonkhet. You also get a deck builder's guide with tips about building the best Magic decks, a Magic "learn to play" guide and a full-art reusable card storage box. All the fixed and semi-random cards in the box are from Kaladesh, Aether Revolt, Amonkhet and Welcome Deck 2017.
The Deck Builder's Toolkit contains 12 Amonkhet cards which can't be found in regular boosters. Graceful Cat (#273/269), Tattered Mummy(#278/269), Stone Quarry and Foul Orchard also appear in the Amonkhet/Planeswalker decks. The other dual taplands are exclusive to the Toolkit and are numbered #280/269 to #287/269. Because these cards have the Amonkhet expansion symbol they are officially part of the set.
