Yeah it all comes down to preference. Some people enjoy having answers to everything, if you happen to draw them in time. I don't like trying my luck though, so I usually just focus my energy into one or two things. Also, that deck hasn't been posted as there are decks similar enough that I felt no need to post it. Also, if you're looking for an Arena deck, I'm not sure that's it. That works quite well in PvP usually because of the 100 hp of the enemy, any more than that and you're stretching your luck. Anyhow, hope that helps!
