Each Planeswalker comes with three Theme decks aimed at different levels of play. Theme decks are intended as a tool to help newer players with constructing Decks. Theme decks were added in April 2017 in Release 2.0 of the game.

Each theme deck is a deck of 10 preset cards. Theme decks have no effect until all cards in the deck have been collected. Thereafter, the Theme deck acts like a Deck slot with a preset deck which can't be changed.
The first time each theme deck is completed, a reward is granted.
| Theme deck | Completion reward |
|---|---|
| Beginner deck | 1,000 
|
| Expert deck | 5 
|
| Master deck | 20
