How about a casual/Multi-player review of some of the new cards? I picked out a few and made a comment or two.
(note: This is strictly a short Casual/Multi-player review of a few cards and my first thought.)
Symbiotic Deployment 2G 
Enchantment 
Skip your draw step. 
1, Tap two untapped creatures you control: Draw a card. 
Rare 
Its going to be quite abit of fun with Awakening and maybe Aluren. 
The Penumbra guys should be good for Multi-player.
Suppress 2B 
Sorcery 
Target player removes all cards in his or her hand from the game face down. At the end of that player's next turn, that player returns those cards to his or her hand. 
Uncommon 
My first thought was the Blue Avatar. Then I thought, is this a semi-Time Walk?
Necravolver 2B 
Creature - Volver 
Kicker 1G and/or W 
If you paid the 1G kicker cost, Necravolver comes into play with two ? counters on it and has trample. 
If you paid the W kicker cost, Necravolver comes into play with a ? counter on it and has "Whenever Necravolver deals damage, you gain that much life." 
2/2 
Rare 
This is almost a Black Kavu Titan.
Ice Cave 3UU 
Enchantment 
Whenever a player plays a spell, any other player may pay that spell's mana cost. If a player does, counter the spell. 
Rare 
This should be real crazy in Multi-player.
Ceta Sanctuary 2U 
Enchantment 
At the beginning of your upkeep, if you control a red or green permanent, draw a card then discard a card from your hand. If you control a red and a green permanent, instead draw two cards, then discard a card from your hand. 
Uncommon 
Its probably a really bad card but the first thing I thought of was some kind of Reanimator deck.
Emblazioned Golem 2 
Artifact Creature - Golem 
Kicker X 
Spend only colored mana on X. No more than one mana of each color may be spent this way, 
If you paid the kicker cost, Emblazioned Golem comes into play with X ? counters on it. 
Uncommon 
I'll probably put a couple of these in my casual Domain deck. It really depends on whether
it as any power and toughness to begin with.
Dragon Arch 5 
Artifact 
2, T: Put a multicolored creature card from your hand into play. 
Uncommon 
Should be interesting with the Invasion and old school Dragon Legends.
Quicksilver Dagger 1UR 
Enchant Creature 
Enchanted creature has, "T: This creature deals 1 damage to target player. You draw a card." 
Common 
This might be a lot of fun on that Urza's Saga crab.
