Any effect can be "epic". . . I remember when Bob Jardeen first introduced the Rubber Band Trick (?handcuffs?) and how it was blowing magician's minds AT THE MAGIC CASTLE for most of the summer. It was an "epic" bit of business because it was something others hadn't seen before, BUT we've seen the same thing (reaction wise) when someone offers a new spin on an old chestnut; such as Burger's handling of the Gypsy Thread or when a certain young buck shows up at the Castle and does a single handed DL -- he literally popped the cards into the air and caught them and not one single bit of suspicion could be laid onto the bit. . . the only way we knew that he was doing this is because we knew the effect and how it had to work.
My point is (and it's been said thousands of times) an "Epic" effect is what we create and what is typically attached to a given performer/innovator. I used to get big kudos for my Cups & Balls because I did some very unique moves and to quote Vernon "one very ballsy move" that no one else had done before me (apparently). Today we have a lot of people replicating those moves (sadly, Mike Ammar tends to get the credit -- gotta love the politics of this business). Ignoring such things, it's the 5-minutes of fame one gets by creating a solid and exciting piece that makes it "Epic", don't expect it to last longer than that and don't try to find the holy grail of whichever niche in magic you work with; it doesn't exist! As the Arthurian tales point out, the grail is within you -- you and the magic are one and as you thrive so will your magic. . . it's something to think on.
