- Not clear when to play the labyrinth cards to remove damage from Hercules. Since I was getting wiped out so quickly in the first two games, I decided to apply whenever - ie even as soon as immediately when taking new cards for hand at end of turn. I also applied any discards that were labyrinths when cutting back to the 5 card hand rule. Given I still didn't win, I think it's ok!
I play it like another card from my hand when I need it.
- The spell card I posted about in a separate thread I later discovered in the manual that it most likely means apply damage to 1 creature of your opponents or all creature in both player decks. And the variant in the manual for solo play is all opponent creatures only. So I always applied that and never just one creature. It's brutal and can decimate your deck, but again I managed to get to the last 3 cards so could conceivably win with some lucky card draws and purchases.
I think that in this scenario, that's a question of rythme. when to apply the fall of Omphalos and when wait.
