 Other rules clarifications
The pious trait adds a relatively slow one-time trashing effect on gaining cards. Pious cards are always at least as attractive as they would otherwise be, because the trashing is optional. They are usually slightly more attractive, but not dramatically more attractive because the effect is one-time and relatively weak. Pious thus can make a strong card slightly overpowered, or an otherwise weak card more viable.
Buying or gaining multiple pious cards can facilitate the construction of a thinned engine on boards where there is some trashing but the trashing would otherwise be too weak to build an effective engine, but pious cards alone are not usually sufficient to build a thinned engine. More often, pious merely provides an incremental boost in the early game, when buying cards for just about any strategy, as it tends to trash an Estate when gained in the opening. When the pious card is attached to a card that plays well with a money strategy but not an engine strategy, it can shift the balance slightly in favor of the money strategy.
