Against Aggro Paladin Primordial Glyph is the key and you need to actually use resources like Frost Bolt to clear things and keep board even or on your favor - otherwise the Glyph needs to help you in the situation.
Warlock is preety easy. Mulligan for early drops (Sorcers Apprentince is not a good one because it have only 2 health and Warlock 1 drops have 2 attack). Dont play Burning Secret against his 5 mana 2/2, go face with spells after turn 6 when the 3/9 taunt is on your way and ignore completly the board. You'll win most of the time.
