The strategy doesn't line up sometimes, but honestly I've had the easiest / less stressful time fighting Slitherspear with this deck.

 Hi guys, Konf here.

So far Heroic Slitherspear proved to be the most annoying boss to beat (to me, at least) and I struggled for a bit. As I was miserably failing with Paladin, I noticed at some point that Slitherspear can easily fill his board by turn 4 or 5, with most creatures being 2/2's or Hungry Nagas out of his Hero Power. And that’s where the idea for this deck came to my head, as I thought to abuse that fact.

Game Strategy:

1) Play your Lightwell / card draw;

2) Let Slitherspear fill out his side of the board;

3) Mass Dispel most of the damage off the board, leaving a few legitimate creatures (by "legitimate creatures" I'm referring to minions that have 3+ attack after dispel);

4) When the board is full – manipulate its state by killing legitimate creatures with Shadow Word: Death or Holy Fire;

5) Slitherspear plays 7^th creature through his Hero Power, which you can Silence / Mass Dispel to being a 1/1;

6) At this point there isn't much pressure on the board and with Lightwell, your Hero Power and Power Word: Glory you can easily out-sustain all of the damage;

7) Play filler cards to keep your hand empty while waiting for combo pieces. Filler cards include Mind Blast, Holy Fire, Power Word: Shield;

8) Finish him off with a Lightwell burst, buffing it with Velen's Chosen, Divine Spirit x 2 and Inner Fire.

 Important Notes:

• Beware of playing creatures on the board after Mass Dispel, as you don’t want him to trade and play more legitimate creatures;
• Sea Reaver draw can ruin this strategy (as it kills all 1/1’s), but in my case his hand got full so quickly that he actually burnt them, so it wasn't much of a threat. Just watch out.
• Don't play Velen's Chosen on your Lightwell until you have the burst combo, as you don't want him to trade and play more threats.

Enjoy!
