Another thing that I have found useful is not being super conservative with the Coin. A lot of new players treat the Coin like its something they need to save for as long as possible and in many cases the game is almost decided by the time they use it. There is nothing wrong with using the Coin early to gain the ability to play a card if that card is going to give you a strong board position at that moment.
Yeah you should use the coin fairly early on. Basically take a look at the cards you have after mulliganing (which is the initial phase where you can decide if you like the cards given to your or not and swap them out) and determine what the best use of the coin might be in your matchup.
Another important tip: You really need to get a feel for all the classes and what their capabilities are. That way you can get an idea of what they might play on certain turns. Example: Mages can play a spell called Flamestrike on turn 7 (or 6 if they have a Sorcerer's Apprentice out!) that does 4 damage to all your minions. So in that case you may want to hold off putting more minions onto the board that have 4 or less health, in order to avoid this. Keep in mind though that there are many variations of decks for each class that can run very different cards .
It's still very early days for this game. I've been playing way too much of it, but still loving it. I've even been watching some streamers and listening to a Hearthstone specific podcast. Someone help me!
Texting is a fine form of communication when you really know someone well and know how they talk and think. If it's a new friendship or relationship it's much dicier. It's harder to tell if they are being sarcastic or serious. You also don't know how quickly they respond and start to get paranoid. I've been there too.
I get what he's saying, I really do. I have bought a lot of games on sale, including retail console games and digital games on Steam or with PS Plus discounts, and I am probably never going to have time to even play most of them. Also because I have so many, I feel like I should be starting another one instead of replaying one immediately after finishing. So I understand his thinking, but c'mon son...GET PAID.
