Once Red Nova Dragon is summoned it's main objective is to destroy, I mean, having it on the field for a long time is suicide, since there are so many horrible stapled cards that can rip through it. Personally I would go for Shooting Star Dragon; it's not that hard to get on the field, plus its sexy, so yeah.

I'll admit Junk Destroyer is a good card, but once summoned Bottomless Trap Hole can take it out, it's effect not being able to activate, thus wasting quite a few monsters. >.<

One card that I think needs a mention is this fella' ;

Spoiler:

This guy is win. His ability to make any "Warrior" monster... I mean, a monster that has "Synchron" as a tuner, it now can tune up in the Chevalier De Fleur, and... well you go ;D
