The advantage given by this deck is amazing, not only does the scrap engine works well but for that little extra the rose dragon engine works amazing. Check the link to see how with only 2 cards in hand you end up with a 3 negates Apollousa, Bow of the Goddess, a 2 counter Borrelsword Dragon, a rank 4 of your choosing, Herald of the ArcLight, and an Ultimate Conductor Tyranno.
