Minimum bans: 0
okay okay, minimum bans: 5 (2 in-element, 2 out of same out of element, one other, something)
Maximum bans: 16 (1 in element, 11 out of each out of element, 2 other, 2 from either other or two different out of element)
could be 17 if you ban nothing in element, but... well, okay, maximum = 17.
That is less than 10% of the available bannable card pool. Why is this too much?
