Boros Challenger Discussion

Just to mention, the situation 2 from Argy's post will not happen as described.

If you have a Goblin Banneret and a Boros Challenger and 0 available mana, while you control a 1/1 White soldier token with lifelink, you will not get the mentor trigger from the goblin (because of reason 3 described below). Mentor needs the following conditions:

1/ A creature with mentor with power > another creature.
2/ Both to be attacking.
3/ If 1 and 2 are true, mentor will trigger and target the smaller creature.
4/ If the smaller creature is still smaller than the mentor upon resolution of the trigger, it will get the +1/+1 counter.

For the same reason, mass pumping like Make a Stand will not help mentoring as they do not create power imbalances - the difference in power between the mentor and any other creature remains unchanged.

To enable mentor, you need combat tricks like Pack's Favor to be cast prior to attackers being declared. For example, if you have a 1/1 without mentor and a 1/1 with mentor, and cast Pack's Favor on the mentor prior to attacking, you will trigger it and attack with a 2/2 and 4/4.

Hey SSK, nice new deck, but why are you limiting your options? I think Boros can be a pretty powerful deck in Standard with Angels and Knights (Knight of Grace, History of Benalia and Lyra Dawnbringer). Why playing cards from only Guilds of Ravnica? I don't think playing cards from other Standard legal sets is taking away the flavor of the Boros Legion on Ravnica.

If you're limiting cards only from Guilds of Ravnica then you're going to want to count on Aurelia as you're finisher and best mentor enabler (3-4x Aurelia) you want to consistently curve into her turn four. I'm not a fan of Captain I don't think she does enough for a four drop. Her difficult mana cost with 3 toughness is what turns me off because the reason to play her in the first place is to be able to redirect damage that's done to her to your opponent (it's a strong ability).

3 toughness is not enough toughness to take advantage of this ability without using other cards to protect her, give her indestructibility (Make a Stand, Sheltering Light, Assure). 3 toughness is not enough toughness to consistently be able attack with Captain turn five without help. Integrity helps to pump her, but this means using another card to make her good. She really should of had 5 toughness especially because of her difficult mana cost.

Consider Healer's Hawk as your one drop? Hawk is good with mentor because it has flying and lifelink, both these abilities can take advantage of +1/+1 counters. Having a one drop who can take advantage of mentor can be helpful to better curve out, but top decking Hawk later on in the game is not good.

Consider Legion Warboss? Warboss can take over a game if left alive. His mentor ability is a bonus, the main reason to play him is because he makes a creature each combat. Warboss is especially good in control matchups where your opponent will not have many creatures to block therefore consider him as a sideboard card?

Consider Venerated Loxodon? I've been playing Loxodon in my aggro Selesnya Elves deck, Elves of Ravnica. Loxodon is very good with one and two drops in fact he's a better mentor enabler then a lot of other Boros creatures because he can put counters on a lot of creatures (up to five of them) at one time. He puts a counter on each creature you use to convoke him this can put a lot of power on the battlefield. I very much like Loxodon with Thorn Lieutenant and Boros Challenger is your Thorn. Loxodon's 4 toughness is nice to survive Deafening Clarion as well as getting lifelink. Consider 3-4 Loxodon?

Consider this creature base:

  • 4x Hawk
  • 4x Challenger
  • 4x Swiftblade
  • 3x Stalwart
  • 3x Tajic
  • 4x Aurelia
  • 3x Loxodon
  • 1x Legion


  • 4x Challenger
  • 4x Swiftblade
  • 4x Stalwart
  • 3x Tajic
  • 4x Aurelia
  • 3x Loxodon
  • 1x Legion

Justice, Integrity / Intervention, Response / Resurgence and Clarion these are all good Boros spells especially Justice. Another card I'm playing and having good success with is Conclave Tribunal. The convoke makes this a powerful removal spell especially when playing a lot of two drop creatures. Tribunal gives you a catch-all removal spell for the main deck. More of it can go in the sideboard or all of it main deck.

Consider this other spells base:

  • 4x Justice
  • 4x Integrity
  • 1x Response (more in the sideboard)
  • 2x Clarion (more in the sideboard)
  • 3x Tribunal


  • 4x Justice
  • 2x Response (more in the sideboard)
  • 4x Integrity
  • 3x Tribunal

The combination of Justice/Tribunal/Integrity is nice. Justice/Tribunal can deal with everything you need to remove in Standard. Justice alone can target a huge amount of problematic creatures, but it can't target your opponent's Aurelia, Shalai, Voice of Plenty, Thrashing Brontodon and a few other annoying creatures. It can kill the big stuff that will roadblock the battlefield or just kill you (Doom Whisperer, Lyra Dawnbringer, Ghalta, Primal Hunger, Nullhide Ferox, Demanding Dragon). Because Justice can kill all these creatures that's why I like it much more main deck instead of Response.

Clarion is a strong main deck card when you're playing more Angels especially Lyra, but it's risky to play with so many two drops unless also playing Ajani, Adversary of Tyrants who can reanimate or pump two drops. Relying on Tajic to save everyone is a not a good game plan because in response to casting Clarion your opponent can kill Tajic and then you wipe your own battlefield. It's situational therefore it might be better in the sideboard. You however want it in some matchups such as Selesnya Tokens, Goblins, other aggro.

Consider this final example:

  • 4x Challenger
  • 4x Swiftblade
  • 4x Stalwart
  • 3x Tajic
  • 4x Aurelia
  • 3x Loxodon
  • 1x Legion

Other Spells

  • 4x Justice
  • 4x Integrity
  • 2x Response
  • 3x Tribunal

  • 24x Lands

The sideboard is where you're going to really miss having cards from other Standard legal sets especially Dominaria. For the sideboard I suggest including draw. One of the reasons that Boros could fail in Standard is the color combination lacks draw. Once you run out of gas if you didn't win the game then you're stuck, relying on the top of your library. Many other color combinations in Standard don't have this problem. Dawn of Hope and lifegaining sources can be a sideboard plan for Boros. Lifegain is another reason that Healer's Hawk can be an option because Hawk is good with Hope. Every time you attack with Hawk and do combat damage you gain life as a result pay and draw a card. Hawk as a life gain enabler is however problematic because it's a creature, easier to removal a creature than anything else.

Sources that can gain life without the use of mana are welcomed because then you're only paying two mana to draw a card, which is great value. Combine Hope with Ajani's Welcome or Fountain of Renewal. Renewal gives you a constant source of 1 life gain each upkeep for no additional mana cost and it can be saced later on in the game to draw a card. Welcome is worse than Renewal because to gain life you have to play a creature which means consistently you have to use more than two mana to gain life.

Welcome is however good with Legion Warboss because he can make a creature for free and you want both Warboss and Hope in the same matchups. But this set-up requires three cards (Warboss, Hope and Welcome) which is much harder to assemble than only two cards (Hope and Welcome). Hope itself can make a creature which is good with Welcome later on in the game for six mana each turn make a token, gain 1 life and draw a card.

Sideboard choices to consider:

Deafening Clarion, Dawn of Hope, Ajani's Welcome, Legion Warboss, more Response, Experimental Frenzy, another Legion.

Good luck with your deck.

Great I'll throw it in.

My only other issue now is that I don't have a full player of anything. I have 3x Boros Challenger but only a max of 2 of everything else worth putting in. Also can't decide on which creature to use between Sunhome Stalwart or Fresh-Faced Recruit. One has constant 1st strike but the other has the mana colour flexibility. Opinions??

Boros aggro is your best shot. Boros Challenger, Swiftblade Vindicator, Tajic, Blade of the Legion and Aurelia, Exemplar of Justice are all top notch threats.

Deafening Clarion, Integrity / Intervention and Response / Resurgence are all top-notch non-creature spells.

Additonally, Boros can roll into aggro once Rakdos arrives in a few months.

You can use any print as long as at least one is legal in Standard. Old Guttersnipes are just as good as new ones.

Thanks! I'll look more into these changes and your suggestions. I have a play set of the 2 drop guy. Boros Challenger I need to get more Tajic. I dont even have an Aurelia (probably something worth investing into). As for lands, I could up the Clifftops to 4 and add couple of more basics. I'll think about Chainwhirler in the long run. Thanks again fro your help!

Yeah, I think your curve is way too high for creatures. Maybe make room for Sky Terror and Boros Challenger. I appreciate that you want to make an angels deck, but the converted mana costs are way too high. You need to get in some additional cards. Dauntless Bodyguard and Skymarcher Aspirant are good 1-drop creatures that could add early board state, and Dauntless Bodyguard can help protect an angel a bit later in the game.

Looks like a fun deck to play, but it looks slow. I think trimming angels down to make room for some more aggressive creatures would be good.

Cool concept, though! +1 from me!

Thank you for the comment multimedia

I'd been planning this deck with the intention of pushing for the Truefire Captain & Star of Extinction. Whilst this is very narrow I was hoping to get the surprise element of these to work against the Standard competition at my local group, who rarely play standard.

I love all of the suggestions you made and really appreciate any help at all. I don't know what I would be best removing to fit these in. Boros Challenger was a card I really wanted to put in but I am still new and still struggling to learn about synergy and manna curves.

Thank you again for your comment. I shall look at these suggestions in depth.
