Basically look for toad and a weapon. Keep Naralex only against control. Keep cultist agains aggro.
Poison rogue but more control to survive aggro. Yet it still has enough damage to take down most control matches.
honestly, Toad of the Wilds is such a good card that fits pretty well on the deck, you always want it in your starting hand.
Death's Head Cultist is for extra survavility as rogue may struggle against aggro matches.
Archdruid Naralex was included initially for the flavour (nature rogue) but i thinks its just pretty solid in the deck, especially against control matches.
Maiev Shadowsong best usage is to take down a taunt in the last turns, or remove temporaly a troublesome minion, especially if it has deathrattle. It also can put Archdruid Naralex back to sleep for extra value, but that is very situational.
I think playing with just 3 weapons is enough, but i decided to use 2 copies of Self-Sharpening Sword because Swinetusk Shank can be a little tricky to pull of in the early game and needs to much sinergy.
