For a moment I looked at what you said about decking out thinking "But False Gods draw two cards a turn..." and then I remembered that they only draw one if their hand is full. The AI would have to be programmed to continue to use mindgate as it gets low on cards, though- currently it sees them as a sort of hourglass, and stops using them at around ten cards left. The only other problem would be if she immortalizes everything (ironic), since she would then be unable to bounce a creature to keep herself from decking out.
For the reward- Upgraded relics sell for 1025
, plus there's the chance of anubi, eternities, mindgates, phase shields, bolts, and (though relatively low) towers/pendula as well. mindgates, shields, and relics would be most common (five of the first, six of the latter two), and only phase shields are common FG prizes (gemini), though relics are obtainable through dark matter (gravity nymphs) and dream catcher (purple nymphs)- but both of those are very difficult. overall I'd say it's worth it
Most variants of CCYB use aflatoxin and antimatter these days- the former would destroy her ability to use the opponent's creatures against them, but the latter wouldn't affect her too much- especially since she probably already drew three copies of it! RoL/hope would probably fare a bit worse than against gemini- she can pull her shields faster thanks to her nymphs, and the electrocutor won't help if all the creatures are immortal
Shak'ar would probably own her, though, unless she pulls an eternity after the doll comes out and rewinds it- her nymphs hit hard and the AI isn't that smart.
Thanks for the input, I'll be sure to make that note about mindgates
