Taking Turns is one of the sweeter decks in Modern, even if it remains outside of tier 1. Taking extra turns in Standard while activating some powerful planeswalkers, however, is tough to beat.
Karn’s Temporal Sundering is expensive and has some pretty harsh requirements. Spending 6 mana to take an extra turn is a steep price, but the setup also requires having a legendary creature or planeswalker. Luckily, the perfect thing to do with extra turns is to start activating planeswalkers multiple times. Getting to also bounce their best permanent makes Karn’s Temporal Sundering a really powerful effect.
The planeswalker suite in this deck is as powerful as any I’ve seen in Standard. Chandra, Torch of Defiance hits on every ability—taking down a creature, adding extra mana to cast Sundering, or just gaining card advantage. A couple extra turns can be all you need to tick her up to the ultimate and the game is over. Karn, Scion of Urza is another card advantage machine that has such high loyalty that it will be tough for the opponent to remove. Getting to see multiple extra cards per turn is nice, but this deck also gives you the time to minus Karn to make sure that you’re getting the good cards you need and the Temporal Sunderings to take over. Teferi, Hero of Dominaria can vanquish a permanent for a few turns, gain some card advantage, and has another game winning ultimate. Teferi’s ability to get you further ahead on cards while also untapping lands is great as it allows you to play a bunch of cheap instants to interact with your opponent.
Speaking of cheap instants, you have some cheap red removal to make sure you don’t get run over and to protect your planeswalkers. Magma Spray can handle most of the cheap threats in the format and is the cleanest answer to Scrapheap Scrounger or eternalize creatures. In a format where Heart of Kiran, Gearhulks, and God-Pharaoh’s Gift are popular, Abrade’s stock has never been higher.
You also have some cheap blue interaction. Syncopate can be a good counter early and late, and a couple copies of Blink of an Eye can act as a tempo play, card advantage, or as a mini-Time-Walk after using the plus on Teferi to protect your planeswalkers from a big attacker for a turn.
The only creature in the deck is Baral, Chief of Compliance. A 1/3 for 2 doesn’t have exciting stats, but making your spells cheaper is worth a lot. Karn’s Temporal Sundering both costing 1 less mana and actually making sure that you have the legend in Baral to be allowed to cast it are important facets to the deck. Getting a loot out of casting Syncopates or your sideboard counters does a nice job of making sure that you’re hitting the cards you care about.
Temporal Sundering isn’t your only legendary sorcery as you also have access to Jaya’s Immolating Inferno. Dealing a ton of damage to three different targets means that you can clear off even the most disgusting of boards. Your Sprays and Abrades take care of the small creatures, and while your planeswalkers and Temporal Sunderings do work versus the larger creatures, having an Inferno to clear the board can be great. This can wipe out planeswalkers or players as a nice bonus to an already powerful effect.
In a deck with almost all noncreature spells, Search for Azcanta is going to do some heavy lifting. This will help to make sure that you’re always finding gas to lock the game out.
Jeskai Legendary Turns combines many of the most powerful cards in Standard with cheap interaction and the ability to Time Walk… who could ask for more?
