Let's playtest Codex. It's a customizable card game in development. It's ok if you're new and just want to watch or learn the game.
Last time there was overwhelming interest in continuing with the new combat system. This time, dozens of cards are reworded to work correctly with that combat system. Some other various balance changes:
--Past hero is slightly weaker, and the Undo spell costs 1 more
--Blood hero is stronger
--White's Pressure Point spell replaced with a new spell: Grappling Hook
--Fire spells all cost 1 more gold
--Verdant Tree is slightly different so it's timing works with the new system, which happens to make it slightly weaker
--Marauder (red) is slightly stronger
--Everything with long-range, anti-air, and overpower says the right help text
--Lots of new art
Getting to the venue: the nearest BART station is MacArthur, which is a bit far, but there's a free Emery-Go-Round shuttle that goes from MacArthur station to the doorstep of the Black Diamond cafe.
