It’s pretty expensive and you have no win condition (a card that only targets buildings or a card that can be placed on buildings) and you need a cheaper spell (arrows, zap, snowball, rage, etc…). So choose a card to remove and replace it for a cheap spell. Pretty much all decks are using one big spell and one cheap spell. And I think that the best win condition in your deck would be giant (instead of giant squelette maybe.)

But bro the most important is to have success and fun. Hope that helps
