This is real fun deck to play and it is also competetive. I'm currently in gold league running only this deck.
This deck is a combo deck that abuses entomb and sacrafice. The deck focuses on removing your opponent's units from the board while simultaneously doing damage to them.
For an even more budget version you can replace any 2 cost spells you a missing with Torch
, Vara's Favor
, and Extract
can replace Grenade
. But eventually you want th have all the cards listed in the deck as is.
