Hearthstone deck building & theorycrafting

Turn an idea into a clear deck plan. Choose cards, test your guesses and improve the list.

From an idea to a deck you can test

Deck building means choosing cards that work toward the same goal. Theorycrafting means planning how an idea might work before you have enough games to judge it. Write down your guess, build a first draft, then test what happens.

Start with a Hearthstone deck archetype that fits your goal. An aggro plan needs early pressure; a control plan needs time and useful answers. The card choices should serve that plan.

Follow the guides in order, or jump to the part you need. Examples use made-up situations so you can apply the method to your own cards.
