Can I discard Clone for the ability of Tarox Bladewing?
Why would you think you could?
because clone can become Tarox Bladewing?
Clone can become a copy of Tarox Bladewing, but that doesn't and cannot happen until it's on the battlefield. And Tarox Bladewing's Grandeur activated ability has a cost of discarding another card named Tarox Bladewing. Not a card that can become Tarox Bladewing -- one that is. Since Clone isn't, you can't discard it for the cost of TB's ability.
