Resurrection Priest

Tips:

• Best opening hand cards are of course, Northshire Cleric, Power Word: Shield, and removal cards like Shadow Word: Pain or Shadow Word: Pain. These cards allow you to draw your big minions and last longer.
• Cards like Damaged Stegotron and Witchwood Grizzly are weaker upon playing, but are full-statted upon resurrection
• Convincing Infiltrator is a good removal card as well as a wall card
• Vivid Nightmare can be best used on [Hearthstone Card (Northsire Cleric) Not Found] or Catrina Muerte. Using it on other cards could make your resurrections weaker. 
• Mass Dispel is a good card to silence any taunts or threatening cards as well as to draw into your deck. 
• Inner Fire or Divine Spirit are self-explanatory, use on big minions to double health and then make attack equal to health. 
• Divine Hymn is great to repair your wall minions as well as trigger your Northshire Clerics. 
• Safeguard is a really good card to play if you need extra protection because of its Deathrattle. It can potentially dilute your resurrection pool.
• Make sure you have a large resurrection pool before you play Catrina Muerte, or she won't be of much value. 
• Your Seance spells are great on almost any target, but my advice is to cast them on your Catrina Muerte, as she is a high-threat target that is almost always removed by opponents. 
• The main strategy for this deck is to last as long as possible until you have mana for your large minions. Remove high-threat cards with shadow words, and draw as quickly as possible with your clerics.
