The card text reads: If you play or have played one or more other Moria Orcs this turn +4 power otherwise +1 power.
So my question is as follows:

I play the first Moria Orcs card so it is +1 power
then I play another moria orcs card which is +4 power
So at this point I have 5 Power

my question is does the first card now give +3 extra power for a total of 8 power in the turn
or do I stay with the original 5?
