Boros is Ravnica's guild of militant order, and in Ravnica Remastered it plays exactly like its reputation suggests: assemble an army, attack every turn, and use it before the opponent can stabilize.
Wizards' design team summed up the guild directly, saying Boros is here to assemble an army and use it, with battalion asking you to play small creatures early so you can attack with a crowd, and mentor ensuring even the smallest soldiers grow into real threats.
Those two mechanics come from different Ravnica-block eras, battalion from Return to Ravnica and mentor from Guilds of Ravnica, giving Boros a genuinely layered aggressive identity in this set.
This guide covers what both mechanics actually do, the guild's key cards, and how to sequence attacks for maximum value.
Battalion triggers an additional effect whenever you attack with three or more creatures, rewarding a wide board rather than one or two individually large attackers.
That threshold shapes the whole deck's construction, since Boros wants enough cheap, efficient creatures to consistently hit three attackers by the midgame rather than relying on a couple of bigger threats.
Mentor lets a creature, when it attacks, put a +1/+1 counter on another attacking creature with lesser power, permanently growing your smaller creatures as the game goes on.
That turns Boros's cheap early creatures from disposable filler into long-term investments, since a one-drop that keeps attacking alongside a mentor creature can end up meaningfully bigger by the late game.
Cards like Boros Elite reward attacking with a crowd directly, getting bigger the more creatures join the attack, which meshes cleanly with the battalion threshold the deck is already building toward.
Filling the one and two mana slots with similarly cheap, aggressive creatures is the backbone of the archetype, since Boros wants to be attacking with several bodies as early as turn three or four.
Cards like Lightning Helix give Boros efficient removal that also gains life, which is valuable in a deck that's otherwise spending every card on offense rather than defense.
Prioritizing removal that doubles as a small life buffer helps Boros survive the occasional slow start against guilds built to grind out a longer game.
Equipment and combat tricks like Civic Saber give Boros a way to push extra damage through once the battalion and mentor triggers are already active.
Sequencing attacks correctly, sending in enough creatures to hit battalion before adding a trick, is often the difference between a good turn and a genuinely game-ending one.
Sleeve your most aggressive early picks in matte card sleeves so they hold up through repeated combat-heavy games.
Boros competes with Rakdos for red and Selesnya for white, so watch for cheap aggressive creatures and mentor cards wheeling back late as a sign the lane is genuinely open.
A common mistake is attacking with too few creatures to trigger battalion, which quietly gives up a huge chunk of the archetype's actual power level.
If the early rush doesn't close the game outright, Boros can run out of gas against a guild built to grind, since most of its cards are aggressive rather than built for card advantage.
Holding back one or two cards as a plan B, even in an aggressive deck, gives Boros a better chance in matchups that stall past the point where the initial attack was supposed to be lethal.
Against Gruul or Simic, Boros usually needs to close the game before those guilds' larger creatures come online, since a stalled board favors decks with genuinely bigger individual bodies.
Prioritizing evasive or hard-to-block attackers over pure stat-line creatures helps Boros keep pressuring the life total even after an opponent's blockers start outsizing its own board.
Outside of draft, Boros's aggressive, go-wide identity also carries over cleanly into a Commander build made from Ravnica Remastered reprints, where battalion-style triggers and mentor counters scale well with a bigger board.
It triggers an additional effect when you attack with three or more creatures.
It lets an attacking creature put a +1/+1 counter on another attacker with lesser power.
Yes, its straightforward attack-every-turn plan is one of the most intuitive in the set.
Board wipes or enough cheap blockers to stop the deck from consistently hitting battalion.
Boros rewards commitment to the crowd: three attackers unlocks battalion, and every turn those same creatures keep swinging is another chance for mentor to make them bigger.
Protect the soldiers doing that work in a one-touch magnetic holder once the draft wraps up.
