There aren't too many good, common, cards for low mana battles and I saw that many people don't know which cards to use... The Hill Giant card is an obvious pick for the reason that you have named and stun ability on higher levels is a huge advantage... Stunning one of the few cards in the opponent's deck is a ticket for a win!
I have picked this post on behalf of the @OurPick project and it will be highlighted in the next post!
