This article is total crap.

The higgest fear of a mud player is a swords to plowshares on your colossus, destroying all ur hard work.

Plus chalice is damn good anyway; delver, deathrite, bolt, mongoose..
Its even better in multiples.

on 2 it destroys merfolk.
On 1 it destroys reanimate.
On 0 it gives ant a hard time.

I like trinisphere too, t1 or t2 its really disruptive. Except its less good late game while a chalice still kills cards out of the game. Chalice is the reason to play mud (+metalworker). It punishes greedy decks.
