Based on the pics you shared in your post, I think the process of the browser translating the words into Spanish might have affected the battle graphics and therefore maybe the sounds too. At the end of the battle, the losing team should have no cards showing on the board. Each time a card goes to zero health, it should disappear. So you might want to try a battle without having the browser do the translation some time, so you can see the graphics of the battle and hear the sounds, if you want. :)
Getting more packs will definitely let you move forward in the game. You can buy them for VOLTs and you can get more VOLTs by sending in HBD. One HBD would get you 1000 VOLTs which is enough to buy 2 packs.
There is also a pack Market where players can sell unopened packs. Sometimes I sell packs there at a nice discount so it is worth checking!
And there is a card Market too, where players can buy and sell individual cards. You can check that sometimes too, if you want.
Good luck in all your battles! :)
