Here are some tips for new players that can help you be better and win more games.
Some are more obvious, some are less, but all together should be helpful.
I'll try to be brief:
If you find yourself ending a turn with unspent mana, or having no cards in hand to play, you should definitely change something in your deck. When you get a new card that fits your deck, try it out. It might be good. Try to figure what card you have in your deck that are not that much useful. Having a 8+ cost creatures in your deck, and ending most of your games before you reach 8 mana crystals makes no sense.
If you have two copies of the same non-legendary card, and you are putting one copy of it in your deck, put second copy too. That way your deck will be much more consistent. With only one copy, you will most likely not draw certain card, because most games end before you are able to draw all you cards.
This goes beyond picking a card when you need it and playing it on that turn. Try to anticipate what will you need a turn or few turns before. Also, try to anticipate what cards might your opponents try to pick, and pick them before they do.
Use them smart. Try to get best starting hand you can. Consider your hero power, when planning your first few turns. Take into account what is your opponent playing. Do you maybe need a removal card . Do you go first or second.
Although this is a nice way to earn extra packs, don't feel pressured to achieve as much wins as possible. Getting a legendary pack is really hard. Few rare/epic pack is something to consider and aim for. Even not getting those is not a big loss, you can still buy better cards with $GODS rewards.

This is where you should aim to earn as much as possible. You should play 20 games (With 17 unique opponents, and win at least 7 games). Do this 3 times a week for a maximum reward. I think requirements are easy to accomplish for everyone.

This is a game, so you should have fun playing it. If it's tedious and feels like a chore maybe you should take a break from playing it.
