Does a 'cannot play cards' effect stop only advancing, or also playing from the discard pile and the first four cards?

Question

Accepted Answer

It stops all of them: advancing, playing from the discard pile through effects, and the four cards at the start of a turn. The newer 'cannot advance' wording stops only advancing two cards from the deck.
