You get cards free for playing.  I got Harrison, Cairane, Antonidas and a gold Jaraxxus from free packs so the idea that only paying players have legendary cards is nonsense.

Are you talking about when the arrows briefly point to the wrong target before you or a minion are attacked by your opponent?  I just presumed this was due to lag and the fact they may have 'moused-over' their hero or another target en-route to the actual selected target.

If am am playing the murloc deck I usually will open with young priestess, knife jugglers, basically anything but murlocs.  As soon as you tip your hand that it's murlocs they know that by just clearing them aggressively and hanging on for later turns that I will likely lose.

I know that when I started on Europe it matched me against some real rubes at first.  I won the first game with the default mage deck, it was sad. Once I notched up some wins the opponents got tougher.  

Not sure what is in the OP's deck, but there are many ways to ice the Hunter.  Every deck has 'cheap' combos and there are a lot of 'cheap' decks.  One might go so far as to say that the decks are simply effective.  The nice thing about the game is that it evolves - what wins today may be irrelevant tomorrow.  Trends come and trends go.  RNG plays a huge part so you will lose frequently regardless of what deck you have.  Try playing that 'unbeatable' Hunter deck and you will find that even the might Hunter loses sometimes.  I actually don't mind Hunter because the play is fast-paced, Paladin on the other hand I can't stand.  The idea that Hunter is a universal and nerf-worthy problem is nonsense.

A timed game with mechanics similar to a chess clock.  Each side has say 5 minutes and then it's flag fall and you lose.

It was only one card but I got a golden Lord Jaraxxus.  I dusted it to make my Ragnaros the Firelord.

Silence will be crucial because he has few copies of the precious creatures which power this deck.  I would go with Shaman - use two Ironbeak Owl and two Earth Shock.  The biggest weakness of his deck is it has no significant draw engine* (other than that single Gadgetzan Auctioneer see aforementioned 'silence'), counter that with Mana Tide Totem and Loot Hoarder.  Make sure to include Feral Spirit as it will waste his spells early on.  If you can afford it, Earth Elemental almost always raises eyebrows from the opponent.

* Arcane Intellect is always a problem with mages.

Agree, it needs to get to 4/4 - there is some versatility aspect to consider in that the card is a lightning rod (can trick opponent into wasting removal as prep for a bigger attack), albeit an expensive one compared to Secretkeeper

I got Deathwing in an arena draw, I liked the 'hail mary' aspect so I crafted one.  Later on I went with the conventional wisdom and replaced him in all decks with Rag.  Tonight I play and my opponent had blown his entire hand, but had six minions and a clear advantage to my 4.  It was late in the game and the only card I had was Rag.  I was thinking DW would have converted the loss into a vic and I was right since he played his next draw and it wasn't removal or taunt.  I will be keeping track of these occasions in both directions and will report to this thread later.

Loot hoarders, Knife jugglers, and Faerie Dragons, bet your deck has 1 if not all 3.

This sounds like a great idea for a new card - a weapon which is always active or a card which activates it.

This was more of an unfortunate stroke of luck than a bad play but still funny.  Like Foo above, I was playing Murloc for a daily quest and got a few murlocs out.  Mage goes and drops a secret.  My turn comes and I drop the Murloc Warleader for my attack.  Their secret goes off providing them a copy of my  Murloc Warleader.  Some quick math tells me I can finish them using Power Overwhelming but they concede before I can.

I'm looking at $80 here, like the OP I like the thrill of opening new packs and unlike MTG (or at least the MTG I played in the late 90's) you can get multiple rares.  I'll probably spend more.  In some ways the game has actually saved me money because I was thinking about buying something here or there and I was like oh no, that's 15 packs right there.
