Magic: The Gathering’s release schedule waits for no Planeswalker, and that’s doubly true of Secret Lair, Wizards of the Coast’s series of limited-time cards and bundles.The past year has seen superheroes, Sonic: The Hedgehog, special Final Fantasy cards, and more, and we’ve rounded up the most popular cards from Secret Lair according to the data from the lovely folks at TCGPlayer.With some starting at around $10, it’s also not as expensive as you may think to collect some of these, although prices do jump to over $500, too.The Most Popular Secret Lair Cards Right Now10 - Yojimbo (Solitude) - Rainbow Foil - $538.87Yojimbo (Solitude) - Rainbow Foil kicks off our list in style, with a Final Fantasy card offering a full-art design and a fun creature to boot.Yojimbo is a stand-in for the card Solitude, offering a 3/2 creature with lifelink that exiles a creature when entering and converting it to life gain, and can be summoned at Flash speed.9 - Anima (Grief) - Rainbow Foil - $395.25Anima (Grief) - Rainbow Foil is a reprint of Grief, with some haunting new Final Fantasy art and the ability to discard something from an opponent’s hand.It’s also a 3/2 creature with Menace, which is nice.8 - Knuckles the Echidna - Rainbow Foil - $10.28Something a little more colorful than Grief and Solitude, Knuckles the Echidna is–as you might expect–from the Sonic Secret Lair set.He’s a 2/4 with double strike, trample, and haste for just four mana, and he creates treasure tokens as your creatures deal damage. If you’ve got 30 treasure tokens, you win.7 - The First Sliver - $59.49This awesome retro VHS design is very cool indeed, and The First Sliver is no slouch when it comes to gameplay, either.Once you play it, you can use Cascade to keep the spells coming, and all other Slivers you control have Cascade, too.6 - Ifrit (Fury) - Rainbow Foil - $431.24Another Final Fantasy reprint, this version of Fury has Ifrit in the artwork. It’s a 3/3 with double strike, and deals four damage when it enters.The artwork looks awesome, too, and it’s seemingly more based on the Summon’s Final Fantasy X appearance than his more recent showing in Final Fantasy 16.5 - Shiva (Subtlety) - Rainbow Foil - $329.53Wow, these Final Fantasy cards are super popular. This one offers the ice-flinging Summon Shiva as a reprint of Subtlety.She can be cast at Flash speed, and is a 3/3 flyer with the option to put a card back into a library. If you’re feeling particularly cheeky, you could bounce Ifrit back, draw and play him again, and get that four damage.4 - Sol Ring (Sonic) - Rainbow Foil - $20.91Sol Ring is a Commander staple, offering an easy ramp that’s found in most preconstructed decks, but this art takes it to a whole other level.The Rainbow foil treatment, complete with Sonic and a bright, pinkish ring, makes this an awesome card that’s not all that expensive, either.3 - Mox Opal - Retro Frame - $229.32I love Retro Frame cards, and this Mox Opal looks great. It’s a simple ramp spell for the mid-game, giving mana when you’ve got three or more artifacts.It’s pretty pricey for what it does, though!2 - Magus Sisters (Endurance) - Rainbow Foil - $365.31Our last Final Fantasy-themed reprint gives Endurance a Magus Sisters makeover, letting you pull your graveyard into your library for a sort of soft-reset.It’s also a flash speed 3/4 with reach, making it pretty versatile, and it only costs three mana. Is it worth $365, though? Only you can answer that.1 - Chaos Emerald (Lotus Petal)This one’s a little different, since there are a few variants of the Chaos Emerald card.Functionally, they’re all identical, offering any color mana when sacrificed but costing nothing, but they’re all fetching different prices right now.Here’s how it shakes out, in case you’re keen to add one to your collection:Red - $195.44Green - $186.62Purple - $180.33Diamond/White - $190.54Blue - $155.76Gold - $148.32Teal - $170.43Check out the full MTG release schedule for this year to see what expansions are coming next, including Avatar: The Last Airbender.We've also covered where to buy Edge of Eternities and Final Fantasy Collector Boosters as well.Lloyd Coombes is an experienced freelancer in tech, gaming and fitness seen at Polygon, Eurogamer, Macworld, TechRadar and many more.
