{Hero of Bladehold} with a {Infinite Reflection} on it attack get infinite heros ( i am a little unsure if this works though would the attack trigger still work if they are put in attacking?)
Doesn't work cause {Infinite Reflection} says nontoken creatures enter the battlefield as a copy and hero puts in tokens
Dang that would have been so fun if it worked though!
It wouldn't work anyway. The tokens are created after the declare attackers step, which is when Battle Cry and the token-creating ability are triggered.
