Tabernacle was always a great card.
Cradle was always great, and expensive, but they changed a rule and it ended up being a LOT better. It went from eighty to two hundred almost immediately.
I stopped playing years ago and sold everything I had. Their business model made it impossible to develop a collection and hold some value, the emphasis is on newer and more powerful cards that cycle out, so you're always spending and never gaining any value. Even formats like Modern and surprisingly legacy have cards that leave because they're banned or made redundant by new cards. The only format that's safe is vintage, and a vintage deck is worth tens of thousands of dollars. It will increase with value with time, but it's an enormous investment.
