While I had the same reaction when first seeing Jumbo Cactuar's unique ability for the first time, the difference between 40, 10,000, or infinite damage is fairly negligible when they all have the same outcome by the end of a Commander match

Deck : This is the area where you place the deck from which players draw cards
As Magics production accelerates and its mandate to produce more exciting cards continues, I worry about the overall sustainability of the hobby
