Transmutation happens during deckbuilding, if wms agreed to allow vault to shrink in size in advance because of it they are breaking their own rules. Which is ridiculous, the fact that it was a backroom deal of which no public information was given exponentially increases the outrage on this matter. We want to transmute 6 to 3 cards, too, bringing our vault to 124 cards. This should give us one matchup fewer, too, no? If not, why are wms allowing Light to break their (wms') own rules with their own permission, but not Fire?
