mtg commander decks crimson vow Spirit Squadron Precon Upgrades $20 (The copy becomes a token.) Magic: The Gathering: Innistrad: Crimson

This popularized other cards a few other cards having multiple instances of cascade, from Zhulodok, Void Gorger and Call Forth the Tempest having double Cascade to Apex Devastator having quadruple Cascade

I do like this over, say, Commune with the Gods because of just how versatile your options are in what you can get

Of course, you could print out pretty much anything and it would be hard to tell in a distant picture over a computer monitor

each card is numbered from 001 to 500, as you can see from the above image (though these are placeholder images, showing just XXX instead of a card number!)

You can probably tell that I mostly played Commander from how that skewed which cards caught my attention

It happens in a less aggressive fashion but thats a lot of raw resources to work with from a single three-mana card
