Boros Humans & Tokens
The most usual deck you will find on the web is WB Tokens. It has access to some excellent cards, like Lingering Souls (excellent is an understatement), Sorin, Solemn Visitor and Inquisition of Kozilek.
In my case, I created a RW Tokens deck, because I was compelled towards those colors. Monastery Swiftspear, Lightning Bolt and Young Pyromancer are pretty strong cards and justify this color pair.
This deck is fairly aggressive. It packs early threats, good interaction and some burn spells to finish the opponent.
The deck is fast, is fun to play, has access to good white sideboard cards and is strong enough for your local FNMs. Hope you will like!
-- Cards Explanation --
Creatures
Monastery Swiftspear : A 1-drop with haste and prowess? It's aggressive, it works well with all the small spells and it's always a good draw. A sublime card.
Champion of the Parish : The other card you want to play on turn 1. A good threat that you can easily buff, even if you draw it later during the game.
Young Pyromancer : Another threat that your opponent must kill as soon as possible. Once it hits the board, you should be able to generate a lot of tokens.
Instants and Soceries
Gitaxian Probe : (1) You look at your opponent hand. You can then plan your attacks accordingly. Can they wipe my board? Do they have a threat that I need to bolt or path? (2) It adds consistency to the deck. (3) Your Swiftspears and Pyromancers get immediate value.
Lightning Bolt : Best removal spell. Extra damage to finish your opponent.
Beckon Apparition : A flyer is always useful.
Path to Exile : Second best removal spell. Exile everything that is truly problematic.
Gather the Townsfolk, Raise the Alarm : Tokens, a lot of tokens. Gather has the advantage of producing human tokens, while Raise is an instant.
Thatcher Revolt : More tokens. The haste ability is nice to get immediate value.
Stoke the Flames : (1) It does 4 damage. Sincerely, nobody expects a spell that does 4 damage when the most played burn spells in the format do 3 damage. You can even deal an extra point of damage during combat, when a token blocks or is being blocked. (2) You can play it while you're tapped out, with convoke, and surprise your opponent. (3) This card is incredible while you have Intangible Virtue in play.
Enchantments
Intangible Virtue : The most important card in the deck and the reason why a token deck works. The buff is strong. Vigilance lets you attack your opponent with everything and still have blockers left.
Leyline of the Meek : Since you have a lot of token generators, another anthem effect is well suited. Excellent if in your starting hand, decent otherwise.
-- Budget replacements --
4x Path to Exile -> Maybe Devouring Light
3x Gitaxian Probe -> Maybe Mutagenic Growth
4x Arid Mesa -> 4x Battlefield Forge
4x Sacred Foundry -> 2x Mountain, 2x Plains
The core of the deck is not that expensive, so it should be fine.
-- Sideboard --
Hour of Reckoning : Bring it when your opponent does not interact that much with you and when he also tries to get a massive board.
Mana Tithe : (1) Excellent against combo and all-in decks. (2) Nobody expects a counterspell when you play Boros. (3) Is fun AND surprisingly effective to play.
Boros Charm : Since Pyroclasm and Anger of the Gods are problematic cards, being able to protect your board is primordial. The 4-damage is also very useful. The other mode is not really relevant.
Lightning Helix : Excellent against other aggro decks. Destroy their small minions while getting you out of burn range.
Wear / Tear : Versatile removal for artifacts and echantments alike. This is a reason to love RW.
Shattering Spree : More artifact hate.
Relic of Progenitus : Graveyard hate.
Molten Rain : Land hate.
