1) Does the bot even know how to play unstable portal? It never seems to play it even when it is the last card in hand and I have 2 mana.
2) I have also seen it poorly use tinkertown tech where it won't play the mech first.
3) Lastly it doesn't seem to know how to use time rewind very well and just double summoned a minion because it had the mana to. There were other minions it could've played or even fireballed an opponent's minion to take it off the board.
4) Doesn't attack with minions for free damage. It just missed 4 damage by not attacking with yeti and there was no reason not to attack since it had already attacked with the Harvest Golem.

Overall the bot is still really great and wins maybe 20-40% with my mech mage, so it just takes a lot more time to get the quests done.
