So I got a number of bill tricks that I can perform quite well:

Greed - Daniel Garcia
Devlin Dollar - Joe Devlin
Extreme Burn - Richard Sanders
Four Quarters - Magick Balay

To build a sequence, I thought I could hide the Devlin Dollar in the Extrem Burn stack of 20s. That way I can go from the 1s, to 20s, to a 100 dollar switch.
But how about Greed? Any idea on how to chain this nicely?

PS: AFAIK these are some of the best bill switches. If you know others to complement, please let me know.

How are you planning to go from Extreme Burn to Four Quarters?

Extreme Burn to 20s, then pick one of the bills to perform the devlin dollar switch (say 20 to 100) or four quarters with a 20 bill modified.

But I don't really know, that's why I am asking.

Perhaps you could just reverse the order? Start with a quartered bill type switch, Greed etc., and then go to your wallet to add some bills. Then do Extreme Burn as a climax?

@eostresh good point on the reverse sequence. Extreme burn is the only trick with multiple bills, so it could be used to include one of the other gimmicks.

For example:

1. Start with Greed, ending in a 50 cents coin. Now, because the bill disappeared, reach to the wallet for a new $1 bill. This would be the Devlin Dollar gimmick.

2. Perform the Devlin Dollar switch to a $20 or some other denomination. After the initial reactions, ask the audience to provide one of their $1 bill. This will anticipate their desire to examine the transformed Devlin Dollar bill.

3. Perform 4 Quarters with their borrowed bill, two times, to go back to the original $1. The difficult part here is to wear the TT at the right time (after borrowing the bill maybe?).

4. Keep the borrowed $1 and include it into the Extreme Burning stack. Perform the full stack transformation. Extreme Burn 2.0 offers the option to end up clean by using the wallet, which was needed at the end of step 1, so it's perfect to finish the sequence.
