Stay 'Rost-y (Masters)

Throne Deck By


Cost Curve




Saw someone on ladder playing Rost, the Walking Glacier + Sling of the Chi, realized it was waaaay sweeter than what I was playing, and put this together. Took me from D3 to Masters in a few days, landing in top 100.

Card explanation:

Sling of the Chi - the main build-around of the deck. It provides removal, card draw, and direct damage (with overwhelm units), while also incidentally protecting your stuff from transformation. Needs chonky boiz to enable it, which leads us to...

Rost, the Walking Glacier - the other build-around of the deck. Works amazingly with Sling, since its massive body lets it both shoot things down and draw cards. If your opponents kill it, it comes back to shoot another thing down, and while it's shifted out, you get to draw even more cards until it can start beating down again. Warp is the icing on the top. It does require an almost mono-primal powerbase to run though.
Siege Breaker - only triggers half of Sling, but killing relics is quite relevant. It's also just a big body.
Geminon, the Double Helix - another massive slab of beef. Surprisingly resistant to removal, since the most commonly-played removal options are damage based or monofaction-only like Send an Agent. FFF can be a bit tricky at times though.
Also tested: Thundrus & Snooze and Daraka, Queensguard, which I was underwhelmed by - they just weren't good enough without Sling active.

Permafrost - cheap and efficient way to turn off many threats.
Maveloft Huntress - another cheap way to kill things. Plunder is also very valuable to allow you to hit power drops.
Hailstorm - obligatory anti-aggro card. Doesn't kill any of our beefy units, and Jarral Ascending and Maveloft Huntress can both dodge it when pumped.
Kenna, Uncontained - eats slightly larger things and provides an evasive threat. Like Geminon, quite resistant to removal.

Market Stuff
Transpose - extremely well-positioned in the current meta, since Exploit is everywhere. Also protects Sling from removal, and our face from burn in general.
Jennev Merchant - not the most amazing statline, but more market access is always good. Howling Peak Smuggler is another option, but I appreciate the aegis that lets Jennev Merchant serve as a better speedbump against aggro.
Jotun Hurler - market and plunder fodder, but the Snowball is also useful for pinging down aggro units and popping aegis.
Xo of the Endless Hoard - another market / plunder option. Drawing an extra card with Treasure is nice, and if you ever get to eight power (and FFFF influence), Xo is a massive threat that also triggers Sling.

Other Stuff
Dazzle - counters most relevant spells, protects our stuff from removal, plunders. I don't think it's amazingly positioned at the moment, hence the 2-2 split with Permafrost.
Jarral Ascending - a cheap threat and some incidental card advantage. We run enough spells that it can provide some card advantage, especially when you add in Xo and Jotun Hurler, but it's actually primarily here to eat removal so our beefy units are more likely to live. Its other use is to serve as an early blocker against aggro, and to be an imbue target for Maveloft Huntress so she can eat larger things.
Wisdom of the Elders - some actual card advantage for longer games.

Furnace Mage - eats opposing relics, and particularly necessary for the Sling mirror.
Honor of Claws - usually a safe pick, providing some more card advantage and can throw away our various fodder.
Mortar - kills sites, which we can otherwise struggle with.
Poaching Drake - another anti-aggro option, shrinking a opposing threat and providing a blocker. Probably the card I'm most on the fence about.
Turn to Seed - removal for bigger units.

Powerbase: mostly mono-Primal for Rost and Jarral Ascending, but also including enough Fire influence for our splash cards, and Cobalt Waystone as another way to get face-aegis.


This is a midrange deck. Our primary gameplan is to provide some disruption in the early game so we can win with our beefy threats in the lategame. Sling of the Chi provides an incredibly powerful removal and card advantage engine, and we run a few ways to protect it with both face-aegis and Dazzle. If you don't have Sling available (or don't have units to trigger it), it's going to be more difficult to win... but Rost and Kenna are more than capable of dominating a game by themself.

For the mulligan, look for power - two power hands are almost never keepable, but can be keepable if you have Maveloft Huntress or Dazzle to plunder into a third power. One of the most common ways for this deck to lose is to not hit its power drops and have a bunch of beef stranded in hand, but if you can curve Sling into something big, you'll usually be in excellent shape.

Keeping power open for Transpose and Dazzle is often a good idea on turns 1 and 2, since Exploit is pretty common. Don't run out Maveloft Huntress unless there's something to kill or you need to plunder to hit your power drops - it's much more valuable as a lategame piece of removal than as an early beater. It's also much better to plunder away fodder (Jotun Hurler or Xo) when possible.

In the midgame, you usually want to start developing threats like Siege Breaker and Rost. Rost is always excellent to run out due to its ability to recur after being killed. You may also start to have other threats like Jarral or Kenna active - pay attention to sequencing with them (ex: scouting spells to the top for Jarral, playing Kenna before combat so she reaches her ultimate faster).

In the lategame, look to close things out - we don't have the raw card draw of a dedicated control deck, nor do we have lifegain to stabilize against aggro. Face aegis and Dazzle both help buffer against surprises, so try to preserve them.


After the 3F Cylix and Krul, Xumuc Occultist nonsense that had taken over the ladder for the last month or so, it was really refreshing to get back to my roots - midrange piles of beef with incidental card advantage. Heart of the Vault may be nerfed, but its successors certainly feel up to the task.

Stay frosty, friends!

I like it. I don't have any Kenna, Uncontained, and I'm down 1 copy of each of the other beefy legendaries, so I filled those 6 slots with 4x Guardian of Spring (which is real cheap, triggers both halves of sling, has overwhelm, and combos nicely with Siege Breaker), and 2 copies of Sodi, Wingbreaker (lots of card draw and incidental flying removal).
mookie Eternal Version: 21.02.11
Nice! Yeah, Guardian of Spring and Sodi are both good choices - both were on my shortlist for testing if Geminon didn't work out. I may have to give Sodi a shot myself sometime, since I've been wanting another answer to sites.

I'm also really tempted to play a couple copies of The Throne Room in here. Guards your relics with renewable aegis, can easily create a Daraka, Queensguard for you which triggers both halves of sling and has overwhelm, and can easily end up creating Eilyn, the Rising Storm, which also triggers both halves of sling and comes with an extra 6 damage on her own.

I haven't been too impressed with Xo. I don't think I'll ever play him, so using him just as a Treasure Trove + market fodder doesn't seem good enough to me. And while Geminon, the Double Helix is certainly beefy, no overwhelm and the tough F requirement make him harder to use well. And you'll use his mastery once in a blue moon, but if 100 damage has been accumulated in a match, you're probably already close to winning. It feels too "win-more" to me. I'll probably sub out those 2 for a couple Thrones.
mookie Eternal Version: 21.02.11
Ha, I've never even gotten close to Geminon's mastery - it's effectively flavor text. Playing it entirely due to how hard to kill it is (+triggering Sling). If you're not running into lots of Send an Agent, then swapping out Geminon for something more playable sounds totally reasonable. I think I've only played Xo once or twice, but I'll also freely admit I'm a sucker for market vaaaaaalue. Better if you're running into more control / grindy decks, but can be too slow if you're running into more aggro.

That said, I'm not sure how I feel about The Throne Room - seems sort of difficult to trigger, and does nothing when you're behind. Still, triggering it off Sling + overwhelm units could be very sweet. Let me know how it goes!
Kalikulator Eternal Version: 21.02.11
Throne Room is money. Incidental triggers from your early threats is nice. Nearly guaranteed triggers with sling. But my favorite is when I get to 8P and every spell triggers once, and face spells trigger it twice. I dropped a Guardian and a Hurler for 2 copies.
