Hearthstone Tips and Tricks

General

• don’t miss lethal because there is a great value play
• silence your own minions to unfreeze them or to remove certain debuffs
• try to play on curve unless it’s somehow detrimental (coin is great for this)
• healing minions to full will remove Enrage

Paladin

• ALWAYS keep silence for Tirion
• Equality + Pyromancer/Consecrate (4/6 mana)
• keep Divine Favor in mind vs aggro
• do not overextend (heals)

Hunter

• keep silence / 5 dmg for Highmane
• Freezing: always, Explosive: face, Snake: minion, Misdirection: face
• don’t always maximize board presence (UTH!!)
• play around Houndmaster (4 mana)
• keep beasts off board
• minimize face damage

Warlock

• zoo: minimize face damage, mulligan for AoE/taunt/heal/cheap removal/early creatures
• handlock: beware health(stall the giant drop for your answers), don’t overextend (AoE)
  mulligan for silence/bgh/black knight/removal

Priest

• try to keep early 3 damage spells for the Northshire Cleric (Wrath/Frostbolt/…)
• try to buff minions into 4 attack range, not out of it
• when pinging, remember he can heal minions
• don’t overextend on turn 4 or 5 (Auchenai Circle // Holy Nova)
• Cabal on turn 6!

Warrior

• pressure early (unless he plays typical aggro minions, then play as if it’s zoo)
• try not to give him too much armor with the Armorsmith
• same goes for the Acolyte of Pain
• don’t overextend on turn 5 (Brawl)

Druid

• vs double roar (minion spam) try to keep board clear, stay out of lethal range
• 9 mana: he can do 14 damage with Force/Roar on empty board (+2 for every minion + their base atk)
• play around the 4 mana Swipe / 5 mana Starfall
• don’t waste removal (traditional decklists go very late)

Rogue

• Miracle: keep some sort of removal for the auctioneer, Loatheb/taunt up when lethal nears, play fast! Don’t let him have it easy the first turns.
• aggro/mill (known as Backspace): don’t skimp on cards or you might end up burning cards, other than that play like you would vs zoo/hunter: clear board and minimize face damage

Shaman

• 3 mana: Lightning Storm / Hex!
• don’t underestimate Flametongue Totems, usually it’s best to prioritize killing these
• 5 mana: Bloodlust gives all his minion +3 attack for that turn, don’t be caught off guard!
• 6 mana: Doomhammer + Rockbiter can do 10 damage!
• 9 mana: Al’Akir + Rockbiter can do 12 damage! (16 if next to Flametongue Totem)
• 10 mana: Al’Akir + 2x Rockbiter can do 18 damage! (22 if next to Flametongue Totem)
• kill Kel’Thuzad asap if he plays a Reincarnate deck or you will lose (unless you have lethal)

Mage

• 4 mana: removal! Fireball + Polymorph
• 6/7 mana: Blizzard (2dmg freezing AoE) and Flamestrike (4 dmg AoE)
• Antonidas/Mana Wyrm/Sorcerer’s Apprentice becomes dangerous very fast: kill asap
• depending on how many spells she has used/amount of Apprentices and spell damage on board,15 hp can already be lethal
