(First time contributing so please excuse my noobness) Card not prevented by an effect should be playable ("&& !prevented"), but currently AI says card not prevented is NOT playable ("&& prevented"). Also, not sure why AI doesn't add to unplayable even though its not contained by playableInstants or playableNonInstants. I'm not even sure if we're maintaining ComputerPlayer's decision logic (as opposed to Computer Player7).
* No more game freezes on commanders from disconnected players;
* No more game freezes for disconnected players in started games (on mulligan, yes/no choices, etc);
* Fixed missing ability controller in some choose dialogs (wrong targets for gained controlled permanents);
* Added TODO for next fixes with take turn controllers;
* Fixed that computer was able to target own permanents for bad effects and opponent permanents for good effect;
* Improved target choices on card score (as example: boost most valuable, discard most weaker);
* Tests: fixed false positive tests (AI depended);
* Tests: fixed that test player can't find permanents for some filters/predicates;
* Game: added multiple cards/effects support (old version supported only 1 effect per game);
* Game: added combo support with split and adventure cards;
* AI: computer can see and play cards with dynamic added alternative cost (like Bolas's Citadel);
* UI: users can see playable cards with alternative cost.
