You may have Illusion of the Div enter as a copy of any creature you control except it has “{G}{U}{B}, Discard a card: Create a tapped token that is a copy of this creature.”

Whenever a creature you control becomes tapped, exile the bottom card of your library. You may put it on top of your library. If you don't, Flames of the Forge deals 1 damage to target opponent or planeswalker.
