We discovered during testing for BoM2014 that the real best card ever vs. Dredge is Tabernacle. It was in a Kuldotha vs. Dredge matchup but then we started theorizing on the value of Tabernacle in any matchup vs. Dredge.
The truth is that it slowed it really down.
Plus it is un-unmaskeable and cannot be fighted with Dredge antihate.
Additionally, Dredge pilots board out the combo (Dread Returns +FKZ+ Fattie+Fatestichers if any) to free up some space after board. Some Dredge decks don't even play the combo anymore.
Tabernacle allows you to have 1 or 2 tokens on the table (at the very very max) plus Ichorids to kill you. And this having in mind the Dredge pilot has to draw 2 lands to keep the tokens on the table.
To play any superdedicated antidredge card, Tabernacle seems a good fitting

although we all know its cons $_$
