I am not so sure you noticed this interaction. Earlier in your article you discuss disruption decks not wanting dead draws and any Chalices drawn after Gaddock has hit the board would certainly qualify as dead draws. Changing your Chalice count to 3 would not solve this interaction either. You just said you would include Chalice so you could cut off opposing moxen on turn 1, well you would want maximum chance to do so, so 4 is the correct number.
When I was talking about dead draws, I was talking about the fact that Gaddock is a legend.
Cron Stax ran only 3 Chalices and it's primary purpose was to play Chalice for zero. 3 Chalice even if you only want to hit moxen is not necessarily wrong, as you think. You are balancing the fact that you want to see Chalice against the fact that you really don't want to see a second.
