[Feel free to edit my question, English is not my primary language]
Legacy is a format with a pretty high number of cards available. It is arguably the format with the most possible different strategies possible. Being an eternal format with very low card renewing, I think it is fair to say that decks with names like Canadian Treshold, Reanimator, Jund, StoneBlade(any) or Burn are not subject to drastic, heavy changes or stop being played anymore in the next years. That is why I feel secure posting a question which will contain specific deck names, assuming their strategies will never change. A discard will always be a discard, land destruction won't radically change from what it is now and so on.
What brings me here is this: How to handle massive proactive control (discard, land-destruction and creature killing (mostly by eddict effect)). Yes, I'm talking about Pox (or SmallPox, if you prefer).
As a distruption-based aggro deck, if I don't run counter-Magic at all because I'm purely creature based, how should I handle the adventure of the game? Somewhat playing as Maverick would be relevant.
I know the importance of a sideboard. I know cards like Loxodon smiter and Sigarda, Host of Herons exists. I know the mechanics my decks can use to disrupt my opponent (activating knight Knight of the reliquary in response to a Wasteland targeting my Savannah and so on).
I want to know how to counter the goal of proactive control deck, which is to get me out of fuel and making me unable to come back from it. Should I keep my cards in my hand, creating a card advantage, should I try to go "all-in" and play as much creature as possible, trying to race his life points before he's able to completely shutdown my battlefield with his many warth effects and eddict effects. Maybe it would be preferable to do the smart plays, playing just the cards that respond to his moves, hoping each turns he will not rip my hand, leaving me unable to keep advantage on the game.
Mostly by my own, little experience, I tend to rush him, overwhelm his board, making him unable to deal with the number of creatures I'm able to put into play. Sometimes it works, sometimes he warth and I have no other choices than wait for my slow and painfull death, unable to comeback. That is not a strategy, it is trying to overrun the problem.
I want to know how to deal with the problem.
Thanks in advance.
