This is my FULL cube card list.
Inside this list, there are 3 levels of cube:
Vintage
Legacy
Modern
You may select part of the cards to make random 15 cards booster to adjust the power level of the game you're playing with your friends.
Remove power nine + Oko + Fractured Identity and others if you want a less Vintage feeling. Add them if you want more power.
I don't pay WOTC for any card anymore after being a loyal customer since 1995. A cube is the perfect environment to go full proxies, try it.
