McFlies (Four fly routine) 

A funny and commercial card magic routine that you can get by contacting me through my instagram @joaquinmatas.
The magician shows four cards, with a fly drawn on each of their faces, and deals three blank cards on top each of them. A spectator chooses a packet and covers it with his hand. One by one, the three remaining flies clearly and visually disappear, joining under the spectator's chosen fly. When he raises his hand, it turns out that he pressed too much and the four flies have come together... but flattened!
