RDW (Standard)

As all RDW decks the strategy is to strike before the ennemy can react and for that a Titan's Strength coupled with a Temur Battle Rage can boost a Monastery Swift Spear to a 6/5 Double Strike, Haste, Trample and Prowess.
The burn (Exquisite Firecrafts, Wild Slashes, Fiery Impulses) is mainly focused to bring down blockers, but can be used to finish an enemy.
Impact Tremors and Outpost Siege (sideboard in matchups versus control decks) verywell with the dragon fodders, hordeling outbursts, and dash creatures like Ligthning Berserkers, Zurgo, Bellstriker, and Goblin Heelcutters (sideboard in case of match ups with multiple blockers), the first dealing direct damage when creatures enter the battle field, and the second, when they leave it.
Wooded Foothills and Bloodstained Mires let you thin the number of lands. Since you only need four lands to play, when you start to have 4 lands (fecthes included), its time to fecth.
Sideboard:
Scab-Clan Berserkers is good against Control, dealing a hefty 2 damage each time your opponent counters a spell.
Goblin Heelcutter was mentionned above as well as Outpost Siege.
Roast is Good against decks with many blockers and Abzan Aggro Decks, burning trough Anafenza's and Siege Rhinos.
Reding Volley also, is good against decks with many blockers, but only if the creatures are white or blue, hence why there's two rather than three. It's also good to bring down an attacking Dragonlord Ojutai when playing versus Esper Dragons.
Boiling Earth is good against decks like yours, armies with small but numerous creatures
