Thalia, Guardian of Thraben:Thalia is good against non creature decks by taxing them. First Strike also makes her effective against certain creature builds as well. She really shines against combo decks that want to cast multiple spells in a turn, and can also slow down control by making removal and sweepers cost more. The down side is having bad synergy with non creature spells we might be looking to run. Despite that, Thalia is still very powerful against a broad spectrum of decks.
Leonin Arbiter: Arbiter is a cornerstone of the GW version of Hatebears. It cripples the mana base of most decks in the format, due to fetch lands being a thing. It also stalls out other decks where searching is a central part of the strategy. Also, Arbiter can turn Ghost Quarter into Strip Mine, and Path to Exile into Unmake.
Kor Firewalker
: This card is the best anti burn card we have available.
Scavenging Ooze: This creature is very good against decks like Dredge that put a lot of creatures itno their graveyard, you also gain the ability to nullify the cards that Snapcaster Mage tries to bring back. The only downside to this card is that in multiples it doesn't do too much.
Qasali Pridemage
: A strong utility card, Pridemage's exalted is very useful when trying to get in hits, and with the added Disenchant attached, you can take out cards like Blood Moon and Steel Overseer.
Voice of Resurgence Voice is great against any deck that wants to cast spells during your turn. So basically, good against every control and tempo deck in the format. It also holds value through it's graveyard trigger, which can buy extra turns against aggressive decks.
Selfless Spirit: One of the main problems that hatebears faced was that it was weak to wrath effects, but Selfless spirit changes that.
Spellskite: Skite is particularly good against decks that either want to target their own creatures with spells, or want to kill you with spells or abilities that you can redirect to Spellskite. His redirect ability is also useful for saving your bears against midrange decks, and his 0/4 body survives Lightning Bolt, can absorb Path to Exile, and can block most early game threats. It can also block
Etched Champion
, which is something we traditionally have problems with.
Gaddock Teeg: Teeg pretty good at stopping cards that cost more than 3. He is specifically good at stopping cards that are win conditions for a deck, but is also good at stopping cards like Wrath of God and Cryptic Command. Unfortunately some of the decks he is good against have an excessive removal suite.
Phyrexian Revoker: This card has the ability to neutralize several cards in the format. It is effective against certain combo decks specifically, but has a worthy board presence across other match ups as well. Revoker tends to shine against decks that are light on removal.
Disenchant/
Revoke Existence
: These cards are alright if prevalent in your meta.
Celestial Purge: Effective at removing everything from Blood Moon to Liliana of the Veil, strong meta dependent removal.
Stony Silence: Great against Tron, affinity, eggs, anything that uses artifacts.
Rest in Peace: Outstanding against graveyard strategies.
Kataki, War's Wage: Artifact hate that works well with Collected Company.
Melira, Sylvok Outcast: Melira is one way to stall out infect, as we can usually grind the game out easily when she enters play.
Suppression Field: Hate for decks that play fetchlands and use activated abilties.
Auriok Champion: A pro black and red is very relevent in a format where decks like Jund and Grixis control are prevalent.
Torpor Orb: Good against decks that play cards like Primeval Titan, as well as any other creatures that have effects when they enter play.
Ethersworn Canonist: Good versus decks that want a high storm count, as well as decks like UWx control that want to play many spells in a turn.
Mark of Asylum
: While traditionally a more budget card, this card could definitely see play in certain metas.
Back to Nature: Solid hate for decks like Bogles.
