Cool set but these all are severely undertuned. Houndmaster of nar is essentially a worse veteran archer, making her a 4/5 or the hounds 2/1s would be fair. There arent many structures so chained gor is usually just a vanilla minion, could be a 3/4. Lich is severely understatted and lacks synergy in death, i would make it a magic card and a 3 mana 2/4. Red rider is too low impact, i think he would be very interesting if you bumped him up to 3 attack and increased the regen to 3 (to put him more in line with the power level of amazon heart eater). Reizera could be a 3 mana 1/5, to put her more in line with amplification machine. Visions of despair could easily be 0 mana, since its low impact and your spending a card to do very little it should at least be high tempo which currently it isnt.
