Rules

Every game has its own rules, so does Hearthstone.

Rules make a game simple, and becomes the boundary of a game.

Most of the time, the difference between a winner and a loser is about fairly understand the rules of the games.

Anything allowed by the rules is allowed. Anything does not forbidden by the rules is allowed. Usually most of the players know the first one but only a few players know the second. That makes the difference between winner and loser.

What are the rules in Hearthstone?

1 You can and must only have 30 cards in your deck. Inside your deck, there can only be two identical minions and one legendary minion.

What is the use of this rule?

Very important. You can use this rule to predict opponent's cards. There are several specific cards which are powerful and mana efficient which is a must in every deck.. You can make your strategy based on the card that opponent had used.

2 In every beginning of the game, each player can change the cards on your hand once.

Ya I know it, So what?

Then do you know we can also see which card that the opponent choose to discard? Based on the decision of the opponent, you can predict the cards that opponent possess on hand to decide your strategy (aggressive or passive)  

Usually a normal player will keep  a series cards of continuous mana cost so that we can play it by using full mana effectively. However in special circumstance, we will keep some cards to counter opponents. For example when facing an aggro opponent, we will keep a area damaging spell card to counter it.

3 Each player is given a fixed time each turn to decide.

So what?

The point here is not about how fast your opponent play a card. But the difference of speed that he playing throughout the game. For example, your opponent in early game is a fast decider. However when reach one turn, he spends more time than normal. This situation maybe indicate he has more than one solution to decide.

 

4 You and your opponents can communicate with specific words.

Word is one of the ways of communication. 

Through communication, you can know your opponent well and fake your real intention. For example, you want opponent think that you are making mistakes but instead you want to trap him, you can use Ooops. If you want opponent to think you are an aggressive player, you can threaten him always. If you want your opponent think you are a pro, try to greet him.

5 You can play with the stuffs surrounding the board.

Well, this is just for recreation.
