Here's an old combo I use in my E-Hero real life deck. I play Revoke Fusion, which sends a Fusion monster from the extra deck to the grave, and then summons one of it's fusion material monsters. but if u destroy a strong fusion monster that's hard to get out, you can than play a re-fusion, which pays 800 life points to summon any fusion monster from the grave, Ignoring summoning conditions. it's a lot easier to get out monsters like E-heroes Electrum and Shining flare wingman with this combo

This Does Not Work. When you send a Fusion Monster with Revoke Fusion, it has not been Properly Special summoned and therefore cannot be revived with Cards such as Re-Fusion, Monster Reborn, Call of the Haunted, Etc. Also Re-Fusion doesn't ignore Summoning Conditions.
