Not sure what you're asking here, nor do I understand Provo's objections. SANCTA has offered to trade alphabet to Team Cav for metal casting now as long as Team Cav agrees not to trade metal casting to anyone else until turn 100. Team Cav also would have to agree not to build the Colossus. My suggestion was we try to make that deal with SANCTA so we'd get metal casting now. We would have to agree not to trade it away until turn 100 and would also have to agree not to build the colossus. I've no idea if SANCTA would make that deal with us though.
