Smithore's Jumpstart 2020 Battle Box. This battle box is a clone of DaveJudgment's original 2020 Battle Box. (https://cubecobra.com/cube/list/jmp2020tight)

As of January 2023, it is still a work in progress, assembling all of the cards.

Dave's description of the Battle Box:
Welcome to the Ultimate JumpStart (2020) Battle Box! Here, you'll find all 46 themes: combined, optimized, and tuned for balance.

Some of the rules I followed include:

• Avoid cards being duplicated across themes if possible
• Use as many rare cards from each theme variant as possible
• Cut unexciting cards that don't move the deck's strategy forward

12/6 UPDATE: Tokens added to each theme for easy returning to the box.
