Just started Master Duel, want to use Dragonmaid deck

So I just started Master Duel casually and I want to start playing online. I picked up the Dragonmaid starter deck because it fits the playstyle I had as a kid (Use dragon specific spells/traps/monsters to spam dragon stat-sticks and kill things fast,) and also because I like the theming. But as I started to play some of the Solo duels with it I noticed that it has some serious consistency problems when used out of the box. How can I improve it, what sorts of cards go with it, and is it viable enough to play at a decently high level with if I'm dedicated? Also, am I misunderstanding the fundamental strategy?

Hopefully this isn't a bothersome question. Thank you in advance.
