a more detailed example:
turn 1: pillars, lets say you get lucky and get 3

towers and and 2

pillars, so you can play one of the archers on the first turn. pay 3

, put archer into play
turn 2: fire for 2

, 0 damage, total cost to date = 3

2

turn 3: fire for 2

, 0 damage, total cost to date = 3

4

turn 4: fire for 2

, 0 damage, total cost to date = 3

6

turn 5: fire for 2

, first arrow hits for 10 damage total, total cost to date = 3

8

turn 6: fire for 2

, second arrow hits for 20 damage total, total cost to date = 3

10

turn 7: fire for 2

, third arrow hits for 30 damage total, total cost to date = 3

12

turn 8: fire for 2

, third arrow hits for 40 damage total, total cost to date = 3

14

turn 9: fire for 2

, third arrow hits for 50 damage total, total cost to date = 3

16

turn 10: fire for 2

, third arrow hits for 60 damage total, total cost to date = 3

18

maybe i could reduce the damage and reduce the

cost.
