Forge now has 113 new cards, which brings the grand total up to 4,102 cards. Right now Forge only has only 8 Scars of Mirrodin cards but more cards will be added. Everybody loves planeswalkers because they are so versatile and now you can use Elspeth Tirel.
Forge also supports the new Scars of Mirrodin keyword "infect" which means "This creature deals damage to creatures in the form of -1/-1 counters and to players in the form of poison counters." Infect is a combination of wither, which is cool, plus old-school poison counters. Plague Stinger (1B, 1/1, flying, infect) is a basic, common card with infect while the mythic rare Skithiryx, the Blight Dragon (3BB, 4/4, flying, infect) will definitely be winning some games. He gains haste for B and regenerates for BB.
Zero cost creatures just got upgraded, Memnite costs 0 and is a 1/1 artifact creature. Darksteel Axe is an indestructible artifact equipment that give +2/+0 that costs 1 and has an equip cost of 2. (By the way all cards that have the word "Darksteel" in the name are indestructible.) Tempered Steel (1WW, enchantment) is the new Glorious Anthem for artifact decks, it says " Artifact creatures you control get +2/+2". Tempered Steel will easily be one of the most expensive cards in Scars of Mirrodin.
Forge also supports the keyword "proliferate" which means "You choose any number of permanents and/or players with counters on them, then give each another counter of a kind already there." In other words, add 1 to all counters including poison counters. Keep in mind that proliferate does not use the word "target" so you can choose cards that have protection from blue.
Steady Progress (2U, Instant) says "Draw a card and proliferate" is a basic, utility card while Thrummingbird can be used to proliferate over and over again. Thrummingbird (1U, 1/1, flying) has "Whenever Thrummingbird deals combat damage to a player, proliferate." (I love cards like Steady Progress. It is cool to see sorcery/instant cards with keywords.)

Download - LQ (low quality) Card Pictures (109 MB) - delete your /res/pic/ directory because this file creates a new directory named "pic"
