The very latest Magic set (as of February 1st), Gatecrash features five more new keyword abilities, one for each of its featured dual-color guilds. As we examine these, you might just find another one you want to fit into your deck–there are some REALLY interesting ones here!

Ability Keyword	Associated Guild	Rules Text	More Info
Battalion	Boros Legion	This mechanic means slightly different things on every card, but it always activates when the battalion-bearing creature and at least two others are attacking at the same time.	Battalion @ MTGSalvation Wiki
Cipher	House Dimir	702.97a Cipher appears on some instants and sorceries. It represents two static abilities, one that functions while the spell is on the stack and one that functions while the card with cipher is in the exile zone. “Cipher” means “If this spell is represented by a card, you may exile this card encoded on a creature you control” and “As long as this card is encoded on that creature, that creature has ‘Whenever this creature deals combat damage to a player, you may copy this card and you may cast the copy without paying its mana cost.'” 702.97b The term “encoded” describes the relationship between the card with cipher while in the exile zone and the creature chosen when the spell represented by that card resolves. 702.97c The card with cipher remains encoded on the chosen creature as long as the card with cipher remains exiled and the creature remains on the battlefield. The card remains encoded on that object even if it changes controller or stops being a creature, as long as it remains on the battlefield.	Cipher @ MTGSalvation Wiki
Bloodrush	Gruul Clans	Allows players to discard creature cards in order to give an attacking creature a temporary power/toughness boost equal to the power and toughness of the discarded creature card.	Bloodrush @ MTGSalvation Wiki
Extort	Orzhov Syndicate	702.99a Extort is a triggered ability. “Extort” means “Whenever you cast a spell, you may pay 1 black or white mana. If you do, each opponent loses 1 life and you gain life equal to the total life lost this way.” 702.99b If a permanent has multiple instances of extort, each triggers separately.	Extort @ MTGSalvation Wiki
Evolve	Simic Combine	702.98a Evolve is a triggered ability. “Evolve” means “Whenever a creature enters the battlefield under your control, if that creature’s power is greater than this creature’s power and/or that creature’s toughness is greater than this creature’s toughness, put a +1/+1 counter on this creature.” 702.99b If a creature has multiple instances of evolve, each triggers separately.	Evolve @ MTGSalvation Wiki

Which Ability is Right for You?

• If you love playing creature-heavy decks (especially with lots of weenie creatures) and attacking all out every turn, Battalion is your new favorite ability.
• If you like to put extra abilities on creatures, but hate how easily Enchant Creature cards are destroyed in-game, you will DEFINITELY want to try Cipher.
• If you always end up with one creature out on the field and three or four in your hand unable to be played (due to mana problems, etc.), Bloodrush will work wonders for you.
• If you already have a Black/White deck, or if you’ve always been intrigued by the color combo, you’ll want to start gathering Extort cards–it’s pretty much exactly how Black/White has always worked, with a little more punch. (And it’s HILARIOUS in group games!)
• If you don’t like ending up late-game with a bunch of 1/1s sitting helplessly alongside your beefy attacker, having a few creatures with the Evolve ability will help your deck ramp up in strength as turns go by.
