Crack shot is normally a one time use card that does not say it can only be used once per-attack/round, and Tomax Bren's ability works immediately after you discard an EPT. Could you use crackshot twice for the same attack this way and get rid of two of the defender's evade dice?

Bren could use Crackshot twice in a round if he had two attacks (like with Cluster Missiles). The second use would cause Crackshot to be discarded without Bren being able to save it. He can't use Crackshot twice during a single attack because that is only a single opportunity and X-Wing only allows you to trigger something once per opportunity.

Thank you that makes a lot of sense. But I do have a question about the trigger per opportunity, didn't they add an errata to calculation because it didn't have the stipulation of only once per attack and for a while was used multiple times per attack until that errata came out?

There's an FAQ entry that mentions only being able to use it once no matter how many tokens you have, but it's mostly there to clarify that you can use one token with Calculation, then spend a second in the usual manner. It's not an errata to the card's wording.

Calculation hasn't recieved an errata. The FAQ entry is a clarification that each eyeball is not a seperate opportunity for Calculation. It further clarifies that if you spend a token for Calculation that doesn't stop you from spend a focus like normal to change any remaining eyeballs to hits.

Ah yes indeed. Thank you both. It is indeed an faq and not an errata.
