At its best it sets off the more simplified, almost deco style of the art without ending up in camp, like this Queza, Augur of Agonies by Julie Dillon
Sanctuary Warden is a card Im pretty interested in running in a deck like Shalai, Voice of Plenty, where generated +1/+1 counters can be turned into card draw and chump blockers, while shield counters can do the most work under a blanket of hexproof
When Foxglove attacks, you can draw cards equal to the difference between yours and theirs if their hand has more cards
Quite a few collect the vintage cards for the art instead of the history behind the cards
Looking at this, I thought a lot about the most recent set excluding Final Fantasy, Tarkir Dragonstorm, and how this card fits in so well with those recently released decks and strategies
