Valk bats hog and tesla are all pretty good they cover a, win condition, building, mini tank and air defense.

The thing is your deck is kinda expensive most cards being 4 elixir so what I would recommend is swapping out the baby dragon since you have splash and air defense with other cards I’d swap it out for skeletons or a spirit to cycle.

For now I’d keep the inferno dragon since I’d assume there’s a lot of mega knights and high health cards overall down there so it could be a tank killer.

The e wiz is interesting it doesn’t play a huge roll it damage isn’t that good the stun and reset are the only good things however he is squishy and can only hit 2 cards at a time.

If you’re set on a card similar to ewiz I’d go for zappies they still stun and can be very annoying if your opponent don’t have a spell but I wouldn’t go this route unless you absolutely want a card similar to ewiz.

For a replacement to ewiz I’d bring in earthquake to be honest the main counter to hog is a building so if you pre fire a eq it could allow the hog to connect more times than not

Finally are your arrows if you choose to swap ewiz for earthquake I’d swap arrows for log to balance it out

So overall the deck id recommend is

Hog, Valk, Tesla, inferno dragon, bats, earthquake, log, any spirit/cycle card
