While things have been fairly quiet in the world of MTG since last Friday’s massive MagicCon preview panel, they seem to be picking up again now. Not only did we get an all-new MTG Marvel Super Heroes spoiler to chew on today, but we also got to see a pair of particularly exciting new Secret Lair bonus cards. These cards both represent substantial value adds to their respective drops, so you’ll want to keep an eye out for them if you ordered some yourself.
Crucible Of Worlds

– Mana Value: 3
– Type: Artifact
– Rarity: Mythic
– Card Text: You may play lands from your graveyard.
As revealed in a new video from Dwarf Fortress creators Kitfox Games, Crucible of Worlds is a possible bonus card for the Dwarf Fortress Secret Lair drop. This is a true-blue Commander classic, enabling powerful play lines with Fetchlands and Landfall creatures. Since it’s colorless, you can run Crucible in literally any deck you’d like, and cast it with ease to boot. As a result, it sees play in over 201,000 Commander decks according to EDHREC.
This immense popularity has given the card a hefty price tag, with copies selling for $30 on the low end. Rare printings, like the Double Masters 2022 etched foil, go for as much as $48, so there’s a lot of financial potential for this bonus card version, too. Interestingly, both of the Dwarf Fortress creators in the video opened this as their bonus card, which could imply that it’s a guaranteed bonus and not a rare one. If this is the case, then the Dwarf Fortress Lair is a hell of a deal. Between this and Terror of the Peaks, you’re looking at an easy $60 in value here, with the other cards as gravy on top.
Arena Rector

Following on from last week’s retro frame Human bonus card reveals, we saw another card in this range in Arena Rector. This modern reimagining of Academy Rector lets you cheat planeswalkers from your deck directly into play, making it a must-run in Superfriends lists. It’s also a legitimate win condition in cEDH, where it can fetch up Vivien, on the Hunt for early wins in Rocco, Cabaretti Caterer decks.
While it’s not for every deck, Arena Rector is good enough in its niche to see consistent Commander play. This, paired with the fact that the card has had no real reprints, makes it a solid $10 card at present. So far, this means Rector is the best possible pull from the retro frame Humans pool, beating out Seasoned Dungeoneer and Soul’s Attendant. If the rest of the Humans pool is this solid, this could be the best typal bonus card range we’ve seen yet.
