Cards like Greedy Freebooter and Shambling Ghast that reward you for sacrificing them are good candidates
For instance, sacrificing a swamp to play Dark Ritual will only allow you to play one spell or ability requiring at least Three Trips through the Library As in normal Magic , you draw cards from your library
Print a few on card stock, cut them on the solid black line , whole punch them on thr circle & bind them with a binder ring or brad
These cards are still collectible, are generally numbered, and are considered by lots of people, including me, to be part of the general MTG collecting scene
Doctor Who [Time Travel, Fan Favorites, Wild Mechanics] If youre into Doctor Who , these Commander decks are super cool
I'm sure there will be plenty of bulk rares in this set when the dust settles, but hopefully these new, flashy, exciting cards continue to hold some value as the set matures
