Lets say you are casual bronze player, like most of us, what will be your strategy to progress without spending lots of money? Will it be to invest on 1 strong deck and play only with that with minor changes or to invest in 2 or more decks (or even cover all elements?) that are "weaker" because you cant buy all the best cards for each element? And 1 follow up question, if first strategy is better, what element would you recommend to focus on? Long story short - 1 strong deck or 2,3+ weaker decks?

Cheers!
