Secret of Merlin

The Secret of Merlin is the major series power, first seen in season 1. It is found by being the first one to solve various coded messages. Its power as of Season 1, was to allow someone to play this at the same time as idols, and let them look at ALL the votes, and then remove and replace one vote of their choice, effectively getting a much more powerful version of the 'Vote Steal' power.
