Great job as usual to everyone involved! What an amazing piece of software this is.
Just wanted to mention that
Possibility Storm doesn't seem to behave properly with respect to casting Adventure cards. Ali Aintrazi posted a Pioneer deck recently that involves a combo where you get
Possibility Storm out and then play a Sorcery attached to an Adventure. Now, supposedly (and I assume this is correct because this deck was played in a Japanese tournament and Aintrazi himself had video of him playing on MTGO) when you cast a Sorcery on an Adventure card, this is supposed to mill through the deck and find a card that exclusively has a Sorcery type on it. In this case, that card is supposed to be
Enter the Infinite, so you draw your whole deck with that, put
Borborygmos Enraged on top of your library, then play a zero cost
Walking Ballista to cast the
Borborygmos Enraged and then kill the opponent by discarding all your lands.
When you cast a Sorcery half of an Adventure card in Forge, it will cycle through the library until it finds any Creature OR Sorcery card. So usually you'll just find a worthless mana dork and fizzle the combo. Now, the text of
Possibility Storm itself makes me think this is a reasonable interpretation of the rules, because it just says "Card with a matching type", and of course, Adventure cards have both Creature and Sorcery types, but apparently it's not supposed to work that way or else this deck wouldn't work at all.
