I debated having a multi post for this entry, but decided against it. The Tabernacle at Pendrell Vale needed a post of its own! Not that I know anything about any of the decks that it's played in (mainly Lands, I believe, which was mentioned in an earlier post — Rishadan Port).
What I do know is that The Tabernacle at Pendrell Vale (Legends) is currently the most expensive card in my collection. It was sitting around $500, then jumped to $800. It may be worth even more than that now. However, mine has a little visible wearing so it will likely never reach a Mint/Near Mint premium, but I'm okay with that. Given its use in the Legacy format and being on the Reserved List, I can't imagine the price of this card going anywhere but up.
For that reason, this little puppy gets kept locked up, never played, and I'm okay with that. I will probably never own a playset, unfortunately, unless I happen to get lucky and score one in a bought collection. The likelihood of that is slim to none, though.
I can keep dreaming!
Have you played with The Tabernacle at Pendrell Vale? If so, what decks do you use it in? Do you think its price will continue to raise? What's your most expensive Magic: The Gathering card in your collection?
