The original Modern Horizons set was revolutionary for 168澳洲幸运5开奖网:Magic: The Gathering. Released in 2019, this was the first time Wizards produced a product where the contents skipped Standard and became 168澳洲幸运5开奖网:directly legal in Modern. The impetus w🌟as to bring new and ol🐼d cards to Modern for the first time, reshaping the format and bolstering different strategies.

These decks do just as well as their full-price coun💜terparts for half the cost.
And reshape it, it did. Modern Horizons is cited as one of the largest progenitors of power creep in Magic. The follow-up Modern Horizons 2 was even worse in this regard, but it's safe to say the first Modern Horizons set turned multiple formats on their heads, and they've been stuck upside-down ever since.
10 Arcum's Astrolabe
Effortless Mana-Fixing
Arcum's Astrolabe might be the most unassuming broken card of all time. It's hard to imagine a simple bauble that does nothing but fix mana could be problematic, especially when you factor in the restriction of 168澳洲幸运5开奖网:having to use snow mana.
The issues with Astrolabe are threefold: First, snow mana's not really a hurdle in any capacity; you can just play snow basics if you want to. Second, a turn-one Astrolabe gives you near-perfect mana for the entire game, enabling multi-color decks with ease. Third, it cantrips on entering, making the opportunity cost next to nothing.
9 🐟 ꦓ Morophon, The Boundless
Boundless Typal Potential
Modern Horizons introduced three new 168澳洲幸运5开奖网:five-color legends to Commander. The First Sliver and Sisay, Weatherlight Captain are assuredly more powerful cards, but they're fairly interchangable with other five-color legends in their respective archetypes. Morophon, the Boundless, however, seems to poke 168澳洲幸运5开奖网:its changeling head in anywhere it possibly can.
Morohpon's a universal typal commander, especially for creature types that don't already have a legendary creature that explicitly supports them. You could run Morophon as 168澳洲幸运5开奖网:the commander of a Dragon deck, or as a means to play all the best Avatars, or G💖ods, or Elders in one place.
8 𒆙 Crashing Footfalls
The Distant Sound Of Rhinos
Nothing good ever comes from zero-mana 168澳洲幸运5开奖网:suspend spells, but that didn't stop Wizards from releasing a few in the first two Modern Horizons sets. Mox Tantilite behaved itself, but the same couldn't be said of Crashing Footfalls, a card that spawned its own 'Rhinos' decks in Modern.

Mag🍌ic: The Gathering – Modern Crashing Footfalls Deck Guide
Rhinos go💛 brr in Magic: The Gathering's Crashing Footfalls Modern deck.
The trick is building a deck with no cards that cost one or two mana, then using cascade spells like Violent Outburst and Shardlesꦯs Agent to guarantee you cascade into Footfalls every time, putting two 4/4s into play as early as turn th🏅ree.
7 ꧑ Ephemerate
Here And Gone, Twice
Ephemerate is 168澳洲幸运5开奖网:the quintessential flicker effect, which is astounding given it started off as a common in Modern Horizons. Before this, players were still running cards like Cloudshift and Acrobatic Maneuver, which🅘 come nowhere near the raw efficiency of Ephemerate.
A single blink effect is usually worth much more than the mana you spend to cast it, since you're often saving a creature from removal, or re-triggering an enters-the-battlefield effect. Doing that again with rebound for no additional mana is just incredible, and the total package only asks you to 168澳洲幸运5开奖网:invest a single white mana.
6 Force Of Nega𒐪tion
Fixed, Yet Still Broken
Force of Negation was an attempt to create 168澳洲幸运5开奖网:a free counterspell appropriate for Modern, and resulted in a second top-tier free counterspell for Eternal formats like Legacy and Commander. Sure, Force of Negation is a big player in Modern, but it's essentially Force of Will number two elsewhere.
The Modern Horizons sets have had an incessant need to tinker with free spells, and each time they end up producing cards that warp different metas around them. It's not exactly Force of Will, nor is it that far off.
5 ♒ ಌ Force Of Vigor
Free Artifact And Enchantment Removal
Early Magic had this idea that players would tap lands for mana and use that mana to cast spells. "As Garfield intended," as players say. But at some point Magic started printing free spells, and the game hasn't been the same since.

Nothing in life's fre🐈e. But in Magic: The Gatheri𒐪ng? Different story.
Force of Vigor's not technically free, in the sense that you have to exile a card from your hand, but the point is that it doesn't cost mana. Like any free-to-cast card, Force of Vigor can catch players completely off guard, disrupting the boardstate when they would normally assume you can't interact at all.
4 Hogaak, Arisen Nec♚ropolis ﷽
Get Gaak'd
'Summer' and 'Winter' are terms you don't want associated with a Magic card. This usually denotes a period of time where something was so powerful in a Constructed format that it absolutely snuffed out any realistic competition. Such was the case with Hogaak Summer.
Hogaak, Arisen Necropolis is an awesome card purely from a card design perspective: It's an expensive creature that can only be cast using a combination of different mechanics. From a gameplay perspective, it's incredibly easy to get out, immensely oversized on the battlefield, and resilient to removal, since you can 168澳洲幸运5开奖网:cast it from the graveyard.
3 𒅌 Wrenn And Six 🌸
Fair, But Meta-Defining
A two-mana planeswalker's a scary proposition. You could end up with something way too powerful, or a complete flop like Tibalt, the Fiend-Blooded. Wrenn and Six hit something of a sweet spot, but not without consequence.

These planeswalkers are the best options for those looking to build a Gr🥂uul deck in💜 Magic: The Gathering.
While W&6's overall design isn't incredibly pushed, it's the implications of a card like this existing in different formats that gave it a reputation. The ability to pick up a land made it an instant role-player in any decks running 168澳洲幸运5开奖网:Wasteland or Strip Mine, and the pinging effect fields out a lot of one-toughness competition in formats wher💝e Wrenn runs free🉐.
2 Urza, Lord High Artificer ღ
A Phenomenal Debut for Urza
Despite being name-dropped in Alpha and having an entire block of sets named after him, Urza's first appearance on his own Magic card came in Modern Horizons. Urza, Lord High Artificer did not disappoint, and showed off the true power of this 168澳洲幸运5开奖网:well-known character.
Urza's main claim to fame is his ability to tap artifacts for mana. This results in an obscene amount of mana generation, and Urza even comes with his own handy mana sink to use that mana, casting random free spells from your library. It's been a powerhouse in Commander, Legacy, and Cube since his release.
1 ℱ Y🔥awgmoth, Thran Physician
The Yawgfather Of Sacrifice
As with Urza, Yawgmoth's another character that was seeded in ♔Ma🎃gic history, but never received his own prope🐓r card. That was rectified in Modern Horizons, which saw the printing of Yawgmoth, Thran Physician, who became an instant classic overnight.
Yawgmoth's power comes from just how many different bases he covers. He's 168澳洲幸运5开奖网:a phenomenal sacrifice outlet, has discard synergy, 168澳洲幸运5开奖网:proliferates on demand, distributes -1/-1 counters and therefore acts as removal, and even has protection from Humans as a built-in safety𓂃 valve from the most popular creature type in Magic.
