@AncientSwordRage Blightsteel Colossus has the same name as a creature you have on the battlefield, which is named Ornithopter, Blightsteel Colossus, Llanowar Elves, and many other things. You also cast a spell earlier this turn called (only) Ornithopter, and then it left the stack. Wherever it went, in the new zone it became a new object with no relation to its previous existence on the stack.
