Question about timing windows: suppose Onar uses move and Rush as two actions, hitting a hostile figure with Rush and dealing (and suffering) one damage.
Can you play both opportunistic and To The Limit off of this? It seems to me that it would work, since you can play multiple cards per timing instance in other places (e.g., Call the Vanguard AND Fuel Upgrade as Start of Round).
Even if there's an issue there, it seems to me that you can play Opportunistic "during" Rush as the damage is occurring, while To The Limit takes place "after" you resolve a special action.
The effective question becomes: can you rush, deal damage, use opportunistic to move 3, and then attack with To the Limit? Is there a lovely 11-space charge for Onar here?
