What's the difference? I was told they are the same by someone. Were they right?
I was asking because I wanted a gaffed forcing deck.

The McCombical Deck is two decks! It is a trick rather than just a prop.

While you COULD use one deck out of the McCombical deck set as a forcing deck, there are many better ways to accomplish it.

McCombical Deck is something I only perform in the jumbo version. But I love the trick. While part of it works like a Mirage deck, there are not 52 cards (or even close) in the jumbo set decks.

Mirage is indeed a forcing deck.

Both have their place.

Don Alan's "Big Deal" is another version of the McCombical Deck principal.

Thanks guys, I recently got martin lewis's sketchpad card rise, and I wanted to use a fair looking force deck as I'm currently classic forcing the card as I am practicing but I'm hoping to use this in a more professional manner soon and would rather go sure fire

There you go!
