How many times did you actually attack with a Conclave when Fish was good?
in both mono-blue and gayred, countless. They were needed to boost the manland count under standstill. In general, 4 factories were not enough, and still aren't enough, if you are playing any of the classic fish decks that I am aware of.
I'd admit it happend less often in GayRed, but thats why one was taken out. Red was just killing the mana base and 4 could not be added.
