Chaos Gambler

Commander creatures you own have "If you
would flip a coin, instead roll a d6. When you
roll any number of dice this way, you win the
coin flip if you roll a value 4 or higher and you
lose the coin flip if you roll a value 3 or lower."
All you need to make a lot of gold is a little gold.
Except at those times when all you need to have no
gold at all is a little gold. Whether you're a good
gambler or a bad one rarely matters, because no
one can divine the whims of Lady Luck.
