double poll? 
i think if you increase it cost or lower damage but don't destroy your melody. it's will be more useful.
if you build some deck to use your melody... i'm don't think you want to destroy it with only 4 or 5 dmg
im not sure how my logic well work but.......
if it lives Finale can do some huge damage because you can actually put 6 of it in........
if u think about it you will have the note/melody of your element which is alrdy 8/10 damage X 6 would be 48/60 damage...
if it was 3 notes/melodies..... 60l 80...
if you have 4 notes l melodies on play it would probably be almost overkill........
