After a lot of testing, I finally managed to find the deck list that is absolutely viable in current meta. It can stand its ground against agro and also surprise any other tempo or control deck with 30+ damage Leeroy combo. 

The Gameplan: 

You control the board, gathering your pieces, then unleash the devastating wrath of Anduin upon your foes with a highly consistent combo.

The Combo: 

1. Invoke Galakrond twice
2. Be sure to have at least 3 pieces of combo in hand
3. Play  Fate Weaver
4. Play Leeroy Jenkins + Grave Rune + Embalming Ritual + Hit with Leeroy + Wretched Reclaimer to gain 4 more Leeroy's  = GG

NB: If you manage to have more then these 4 key combo pieces in hand and reduce cost to another Grave Rune or Wretched Reclaimer, you can do even more damage

Matchups, mulligan and general advice

• Consider keeping Leeroy vs non-agro matchups
• Remember, you have 2 Grave runes and Wretched reclaimer, don't hesitate to use those if needed. For instance, gaining 2 more Sandhoof Waterbearer or Zilliax vs Agro is usually GG
• You might need 36 damage vs warrior with armor, so keep 2 wretched reclaimers for combo
• Hold your draw minions vs agro and prioritize playing Injured Tol'vir or Sandhoof Waterbearer to get resurrected with Psychopomp

Only matchup that is highly unfavorable for you is resurrect Priest, hard to get through their wall with Leeroy. Rest of matches are fine, you have a good chance vs all

This deck is not easy to play. It is for people who would like to think more on card choice, not only play all cards in hand and win. I am sure that in hands of a PRO this deck might be really powerful. 

Thumbs up if you like. Enjoy!
