Cassandra's understudy ability

[Design Dragon]

So Cassandra has an ability called (1) Understudy: Take a (1) Ca action belonging to target friendly non-leader model within 8". This action may target friendly leader models if they have the Showgirl characteristic. This action may only be used once per Turn.

If Colette gets some (1) Ca actions via upgrades, can Cassandra use those with understudy? If so, does she also have access to the triggers given by the upgrades?

[Bengt]

Yes and Yes. Unless a copy action effect explicitly says "on stat card" (e.g. Sandeep), you can take actions from upgrades. Triggers would also need to be explicitly excluded (e.g. Doppleganger).
