This season i bought all the epic chests and with the season end and some random chests i finally was able to max my epic reward cards.
1. Arachne Weaver
I think this is the best card of the whole set. Corrupted healing is a great skill! If there is taunt, too then it will even get more and more health and poison of course is always a good skill.
2. Thanalorian Blade
A really nice aggressive card. If circumstances are good it can take out a lot of enemies.
3. Olivia of the Brook
When it came out a lot of people were complaining that this cards is OP. And indeed it can become very strong, but i do not like the rng so much, especially since she dies very quickly.
4. Night Reaper
A very cool anti flying flying card. I especially like the deflection shield on it. Mana cost is quite hight, but when the ruleset fits it is worth it.
5. Shock Trooper
Probably one of the best back to basic cards. Very high damage for the mana cost.
6. Kha'zi Conjurer
Similar to shock tropoper this is probably one of the best red backto basic cards.
7. Halfling Refugee
The halfling is also really good in back to basic, but also not bad as cheap flesh shield.
