Deck Builder's Toolkits

Deck Builder's Toolkits are a series of box sets released on an annual, and later semi-annual, basis. They seem to be discontinued, and to be replaced by Arena Starter Kits.

Going forward in the Three-and-One Model, the Deck Builder's Toolkit has a stronger integration with the revamped core set, Planeswalker decks and the Welcome decks, allowing for an easier transition between the products. In contrast to earlier iterations, all the cards in this product (mostly commons and uncommons) are entirely fixed, providing R&D full control over the experience and allowing them to plan out the deckbuilding options that players will find when looking to upgrade their Planeswalker Decks.Mark Heggen (May 14, 2018).

Core Set 2021, Zendikar Rising and further sets notably lack a Deck Builder's Toolkit.
