Finally managed to beat this stupid boss with this deck. On curve Reno kinda helped.
Made some changes to the deck, with the Witchwood arriving.
The priority is to keep the deck's dust cost low, so I didn't included the following cards, but if you have them, try to squeeze them in somehow.
Made some changes, and considerations with the new Boomsday Project cards.
Rusty Recycler. Has Taunt, and Lifesteal, that makes it a solid budget choice.
Soul Infusion. Not sure what to cut for it, but that +2/+2 can be valuable, if it hits the right target.
