This Deck here can defend and control the pace of the match very well due to the low average elixir cost of the deck. With the valk, inferno tower and e wiz, you're able to defend and quickly setup your miner poison push.
The miner will primarily do tower chip damage but it can also be used defensively in situations where a dart goblin or princess cant be defended against in a bait deck
The valk will be your primary tank and will help distract your opponent's tower from attack your Miner during your push.
The valk will lead the charge and when the path is clear play the miner once the valk crosses the bridge and support with the e wiz and poison. Use your ice spirit and skeletons to kite the opponents and cycle thru your cards back to start another push and quickly defend with the valk and inferno tower
Same strategy but use your miner and poison to do more chip damage while u defend and control.
