The instructions for the warrior state:
For each Traveller you have in play (including this) each other player discards the top card of his deck and trashes it if it costs $3 or $4.
So let's assume I have played some card that gives me +2 actions and I also have two warriors which I play for those two actions.
Does the attack on the first warrior take the second warrior into account (i.e. there are two travellers in play on both attacks, forcing my opponents to discard (and potentially trash) 4 cards)?
Or does the first attack only have the one warrior in play and only the second attack counts both warriors, forcing my opponents to discard 3 cards (1 + 2)?
