This is my personal high powered mini Battlebox.
I focused on the aspect of fun, options and impact.
Each card should have an immediate impact on the game but not be able to win the game by itself. I wanted to give players, who like to play magic but did not spend infinite money on the game unlike, the chance to cast strong and cool cards.
This Battlebox is mostly made up of lots of left over cards I cannot or don't want to play in certain formats anymore (you will see a lot commander cards in the list).

Details to the Battle box:

• 2x Land set (5 basics and allied color filter lands)
• Using the communal deck and graveyard rule (both player sharing those zones)
• Basic land set for cards like Cultivate
• Unlike regular Battlebox there are utility lands in the deck
• I have a personal preference to make the distribution of the cards quite evenly just like a regular cube

I made a reddit comment on how I balanced and approached this format with these individually strong cards: https://www.reddit.com/r/mtgBattleBox/comments/oe0pye/high_end_cards_and_increased_power_levels/h87rpvy/?context=3

Current Goals for this Battlebox:

• Keep this list updated
• Balancing more the Battlebox
• Checking out for interesting and playable un-cards
• Implementing a set of pregame effects which both player are effected/have access to and make the game either more silly or more difficult to play (I will update on this one)
