Cheapest wave 1 hold? (No Snail)

I was wondering what some of the cheapest wave 1 holds are. From my playing I think it's Windhawk. As long as you don't get a snail wave 1 a windhawk will hold with 1HP. I have moved it around on the board to see if that changes anything, but I always seems to survive with 1hp. Windhawk is 85gold

I know Gateguard can also hold (100gold) but I have also had it leak. Bonecrusher also holds at 110 gold.

I was wondering if there was anything else thats super cheap and holds
