The Greek mythology-inspired set of Theros: Beyond Death is live on MTG Arena and there are a ton of new cards to playtest. Boasting an impressive roster of spells that could easily shape multiple formats, it can be difficult to know which ones to spend your Wildcards on. Given how few and far between Wildcards can be for the average player, it’s important to make your investments count. Because of this, when deciding on our list we focused on cards we suspect will have the biggest impact in various MTG Arena formats like Standard or Historic.
Of course, this doesn’t mean you should obtain other cards if you have spare Wildcards. Focus on what your deck needs to improve and become more competitively viable.
MTG Arena Best Mythic Theros Cards
If you’re a fan of Historic then expect to see Heliod everywhere. One part of a two-card combo, Heliod is exceptionally devastating if he manages to stick on the board. Unless Walking Ballista gets banned, this will be a powerhouse in Historic and could easily rocket to the top of the tier list. Even without the combo, Heliod is quite good thanks to its indestructibility and ability to pump your team. It’s also possible that Heliod will find a place in Standard if the White Weenie deck continues to grow in popularity.
Uro, Titan of Nature’s Wrath
There’s a high chance you’ve already run across this card while playing Standard. Uro, Titan of Nature’s Wrath is an absolutely bonkers card that will be one of the best creatures until Theros rotates out of Standard. For three mana you gain three life, draw a card, and possibly ramp. Being able to do this again a few turns later is even more insane. A superb tempo card that oozes value, Uro can rocket you ahead of your opponent with little effort. He also sports a great power and toughness that can block most creatures while providing decent on-board pressure.
Calix, Destiny’s Hand
Do you like enchantments? Do you want to deal with your foe’s creatures while developing your own board? Then Calix, Destiny’s Hand is the planeswalker for you. A bit of a wildcard, Calix has the potential to become a key component in any Selesnya or Bant enchantment deck. Not only cant Calix exile a threat, but he can help you dig through your library for key cards. It’s also important to note that this planeswalker is great for dealing with indestructible gods. While he’s not the flashiest planeswalker around, Calix will certainly be an impactful card in the future Standard meta.
Kroxa, Titan of Death’s Hunger
Rakdos Knights is currently the best deck in the Standard format and it’s only going to get better. Kroxa, Titan of Death’s Hunger is an aggressively costed spell that either hurt your opponent or force them to discard a card. Since it triggers on both Enter-The-Battlefield (ETB) and attacks, Kroax can quickly deplete your foe’s resources, making them far easier to kill. Despite not being a knight, Kroax’s resilience via the Escape mechanic makes him a constant threat that will keep coming back until you’re out of cards in your graveyard. If Rakos continues to dominate the meta, then Kroax will easily find himself a home in this top tier deck.
MTG Arena Best Rare Theros Cards
I love everything about this card. Nightmare Shepard is a four mana creature that could define an entirely new deck. Being able to instantly “reanimate” a creature upon their death opens up a ton of possibilities for unique combos and synergies. Even though you’re not technically bringing the creature back, getting a cheap doppelganger is the next best thing. Imagine playing Gray Merchant of Asphodel and then immediately sacrificing it while Nightmare Shepard is on the board. It’s completely possible that these two cards alone could push Mono-Black devotion to the forefront of Standard. Keep an eye on this one, trust us!
Kunoros, Hound of Athreos
Given the high possibility of Escape being an insanely popular mechanic, Kunoros, Hound of Athreos will undoubtedly become the go-to counter for players. Boasting Lifelink, Menace, and Vigilance, this dog is already a fearsome threat, but its ability to shut down a variety of cards makes him so useful. Any deck that runs black and white will absolutely make good use out of Kunoros. This will be a staple for as long as reanimation and Escape decks are viable.
At first glance, Tectonic Giant may appear to be a mediocre card. Paying four mana for a card that enters the battlefield and doesn’t do anything isn’t ideal. However, it’s the fact that this creature’s abilities trigger either on attack or when it’s targeted by your opponent that makes it so dangerous. Tectonic Giant is unideal to remove, especially if you’re up against a burn or fast aggro deck. Boasting two abilities, Tectonic Giant gives players a nice amount of flexibility that’s rarely seen in Red decks. You’ll either get to bash your opponent for 6 life or essentially draw two cards. An unopposed Tectonic Giant can simply win the game by itself.
It’s a free sacrifice outlet in Standard, do I really need to say anything else? Woe Strider is the key piece that’s been missing from the Rakdos Aristocrat deck that’s been desperately trying to gain traction. Costing just three mana, this terrifying creature comes into play alongside a goat, which you can immediately get rid of to scry. Plus, if it dies then you can use the Escape mechanic to reanimate this foe and give it a slight power boost! Cards such as Mayhem Devil and Judith, the Scourge Diva synergize beautifully with this haunting sacrifice outlet.
Thassa, Nylea, and Purphoro’s Intervention
We’re cheating a little for our last pick, but these three spells will certainly have a place in Standard. Having the choice for what a spell does has always been strong, so it’s no surprise that the Intervention cycle is worth picking up. Each one slots into a different deck, but they all provide great utility. Thassa’s offers superb card digging and decent counterspell, while Purphoro’s Intervention has some nice aggressive options. Nylea also boasts some nice ramp and can take down problematic fliers like Sphinx of Foresight or Cavelier of Gales. If you need to fill some spots in your deck, then pick up a few Interventions and enjoy the value.
