This is the updated F2P tempo list for my alternate account. If you don't own either of the Vilespine Slayers you can replace them with Sap. I do however highly recommend having at least one as it is currently one of the most important cards in the deck.
While this deck lacks a good chunk of important (But expensive) cards like Prince Keleseth, Leeroy Jenkins and Edwin VanCleef. It can still manage to aggressively take the win by utilizing your powerful mid game minions and cheap burst damage. A new card I've been excited for that was recently added in the Witchwood expansion is Hench-Clan Thug, this card is insanely threatening in the early to mid-game and I am glad it can fit in this list only being a common, you will almost always want this in your opening hand as it by it self can snowball into a giant minion your opponent will have a hard time dealing with. Cobalt Scalebane works very well to keep your side of the board strong, while other cards like Elven Minstrel and Shadowstep help you gain the value needed to keep throwing down pressure. The most expensive card in this list (in terms of dust), which of course is Vilespine Slayer, is replaceable by Sap, but I highly recommend having at least one as it is very strong and works very well with Shadowstep.
Due to Baku the Mooneater paladin I decided to keep in the two copies of Fan of Knives as it is apart of the basic set and does well at keeping their small tokens off the board. Shadowblade was a strong card I considered in the past but later found that Deadly Poison fit the deck better as it was apart of the basic set and works well with the other cards that requires a combo activation.
The Basics: The goal of this deck is to push for board control and win by utilizing your strong early to mid game minions. In all match ups, the most important cards to fish for in the Mulligan stage are your early game minions and cheap removal. Cards like Backstab and Fire Fly are going to be the highest priority as they offer the best value in maintaining the board in the early stages of the game. If you are going second, keeping one SI:7 Agent or Elven Minstrel will be a good idea as coining it can swing the board or give a lot of value early on.
Against Aggro: When playing against aggressive decks, maintaining the board in the early game will be the highest priority as falling behind will result in a quick and overwhelming defeat. the most important cards to mulligan for will be: Tar Creeper, SI:7 Agent, Backstab and Fire Fly.
Against Control: When playing against slower decks, overwhelming your opponent early on and gaining the value necessary to keep applying pressure will be important, Elven Minstrel is by far one of the strongest cards in these match ups as being able to draw your threats is absolutely necessary to stay in the game. Shadowstep will be your best friend when it comes to staying ahead as being able to get back another Vilespine Slayer and Elven Minstrel is very important. The Mulligan is very similar, just fish for your early game cards and keep SI:7 Agent if you are going second. Note that Spellbreaker is a must have against Warlock as stopping them from getting out a Voidlord early on will be game changing.
