The "Charge of the Boros" deck shows off what the Boros Legion does well: fight. This fanatical guild merges red's passion and fury with white's battlefield precision to make a sleek fighting force that steamrolls its opposition.

Like any fast deck full of small creatures, this deck relies on having enough creatures at different mana costs. The ideal opening hand lets you play a one-mana creature on turn one, a two-mana creature on turn two, a three-mana creature on turn three, and then multiple spells each turn after that. That's why the "Charge of the Boros" deck is loaded with cheap creatures!

As the game progresses, your opponent will try to stop your advancing army. Your goal is to keep dealing damage by any means possible. Skyknight Legionnaire has it easy—with haste and flying, it'll be difficult to stop. Your ground forces, on the other hand, might need some help. Thundersong Trumpeter prevents your opponent's best creature from blocking, and Cyclopean Snare has a similar function. Your various instants provide even better tools for forcing damage through: Lightning Helix and Dogpile can easily clear a path for your attacking creatures. Play Dogpile after you attack but before your opponent blocks for maximum effect.

Radiance spells work amazingly well when played on a multicolored creature. If you play Rally the Righteous on your Skyknight Legionnaire, all other red creatures and white creatures (in other words, all of your creatures) untap and get +2/+0. If you use the devastating Cleansing Beam on your opponent's blue-black creature, it deals 2 damage to each blue creature and black creature in the game. Be careful if your creatures and your opponent's creatures share a color!

After playing the deck a few times, you might want to change some cards. To improve the deck's aggressive nature, add more one-mana and two-mana creatures like Frenzied Goblin and Veteran Armorer from the Ravnica: City of Guilds™ set. If you like blowing up your opponent's creatures, try more direct-damage spells such as the powerful Char. If you're really adventurous, check out some of the other cards the Boros guild has to offer, like Firemane Angel, Brightflame, and Sunhome Enforcer.

Time Spiral features 301 cards, plus 121 special "timeshifted" reprint cards from Magic's past, with randomly-inserted premium cards. All cards, including the timeshifted cards, are tournament legal. The set includes 121 commons, 80 uncommons, and 80 rares, plus the 121 timeshifted cards with their own rarity.

Starting with Time Spiral, there has been a change in how premium cards are distributed. Previously, premium cards replaced a card of the same rarity, so a premium rare would replace a standard rare, a premium uncommon would replace a standard uncommon, and a premium common would replace a standard common.

In Time Spiral, and in future sets, all rare, uncommon, and common premium cards will replace a standard common instead. It is now possible for there to be two rares in one pack: the standard rare card plus a premium rare (which replaces a standard common).
