Mirage, Servant of the Djinn

Vigilance
While Mirage is in play every source of damage past
the first source of damage each turn that damages
the same target deals +1 damage for each source of damage that has already damaged the target.
{1}: Mirage is no longer blocking or being blocked
by the creatures that he was. He is now blocking or being blocked by the same creatures that another creature you control was blocking or being blocked
by.
