Illusory Status

Enchant creature
When Illusory Status enters the battlefield,
choose a number. Enchanted creature's
converted mana cost becomes equal to
the chosen number.
"Oh I've tricked many men and women into thinking
they rule this city. Most of them died when they ran
into Miss Vinare of course, but they did have a lovely
time living their dream." - Luca, Artist of Illusion
