"Vacuum"?
raw numbers:
Gedy 13P plays 15P
Haunt 13P plays 14P
Passi 14P plays 15P
Siege 14P plays 15P
Ball 15P plays 13P
Highest cost, lowest combo - and poison isn't that strong since Veil.
what? WHat? WHAATT???? How did you arrive at those number? Lets do it correctly now.
Gedy: 6 (4+2) + 6 + 6 = 18 (the first card gets +1 for each alchemy and for the sake of getting the minimum value, lets assume it is not bonded, otherwise, it is 8 + 6 + 6 = 20)
Haunt: 6 (4+2) + 5 + 7 = 18 (the first card gets +1 for each DW units and lets not calculate the DW points they get for free, otherwise, it gets complicated and much more, which it actually is)
Passi: 5 (4+1), 6 + 4 = 15 (but puts two engines on board. I am giving only +1 since lets assume Peaches get triggered after Chapter 2)
Seige: 4+7+6 = 17 (puts an engine which can be played around in most cases)
Feign Death: 6+6+3 (+3 if DB is managed) = 15 or 18 (puts one engine on board, like ever other Scenario, and I would say this is the second weakest engine spawned by scenario, haunt being the first)
Ball: 6+4+4+KillsTheHighestUnit = 14+HighestUnitKilled (puts one of the strongest engines by any scenario). So, even if we assume it only kills a 4 power unit (but it is usually more than that), it is 18 points. But it comes with a removal, the only scenario which can remove the highest unit.
So, Ball's price is justified. What is not justified is Gedy and Haunt being criminally under provisioned.
No bloody scenario should be 13 provisions. And Gedy and Haunt should not be cheaper than any other scenario, as they are equally or even stronger then Seige and FeignDeath. Make all bloody scenarios 15P and I will be happy with that, but keeping a couple of Scenarios which are actuall stronger than others at 13 provisions makes no [..] sense to me.
