I think there's a connection between the trend for eliminating lots of card details and the "oracle-isation" of tarot. It's like people are tired of the RWS and just want cards to mean anything whatsoever. Minimalism enables you to do this. I think the two phenomena are connected.
Now that makes sense. Some of the minimalist decks can be very specific about the emotion or idea (but usually emotion) they are trying to express on a single card. That can work for one card but makes for a challenge with spreads where they can be a bit disjointed.
I don't have much of a hankering for minimalism in any area in my life (some days my apartment looks like the Vatican was having a fire sale) but I'm intrigued by the Linestrider and the Pagan Otherworlds. I couldn't get into the "enter the card" meditative aspect of the Arthurian but the Uusi Pagan Otherworlds seems much more interesting with its empty windy moores.
