How does this work if i play a second or third iron man bleeding edge? | tcgmode

Ie 1: iron man is out, 2: i play iron man 3. I create a token copy of iron man, and sac the original 4. I play another iron man, sacing the original but before it resolves i get two additional token copies of iron man, so now I have 4 once a turn copy machines, 3 of which are non-legend...
