Great work so far, I'm also new to the forum but downloaded and enjoyed the heck out of this Shandalar update. As far as play testing goes in Regards to Thieves Hideout 1,
1) When enemy resolves
Smoke and following through to upkeep the game seems to stall for me because I am prompted to untap creatures I don't even have on battlefield and even if I do doesn't seem to respond to my selection.
2)
Drop of Honey or
Porphyry Nodes seems to ignore my Argothian Enchantresses possibly due to her shroud. I also believe they wont target protection from G or W respectively although that's not how the rules say it works. Anyways I've been abusing my playthrough with endless creature destruction as long as the Enchantress is in play with the enchantment.
As for the future I'm really hoping you add planeswalkers, even though I'm sure its a pain in the butt.
Keep up the good work. I'm sure everyone here appreciates it.
