Alternative erratas:
Caldara: Remove Fortune or Fate after being used. No need to errata Caldara
Háma: Remove a card instead of discard a card to return a tactics event to your hand, and/or remove the tactics event you returned to your hand after you use it.
With the Errata on Caldara, some people might think twice before buying further core sets to get extra copies of Fortune or Fate since that card is now dead. FFG is firing against their own products here.
BTW will we ever see positive erratas? Spirit Pippin, Lore Bilbo, plenty of never-used cards from the first cycles, etc ¿?
