Returning to Mirrodin

With the upcoming release of the 'Scars of Mirrodin' set for the Magic: the Gathering trading card game, I delve into the recently released spoiler list by WotC.

Some initial thoughts:

• 'Metalcraft' sounds like it has potential, especially for any Esper-themed decks.  Reaching back into the vast history of MtG might also reveal some hidden gems too (I'm looking at you Broodstar).
• Myr creatures return, and suddenly building a deck built around artifact lands and Affinity seems viable again (expecially for Legacy format with Broodstar).
• Sword of the Body and Mind... Wow... Just wow... G/U is now viable again, and with R/G/U (mainly Mage Slayer) it just looks like it'll curb stomp most decks.
• LOTS of artifacts in this set (not surprising since we're back to Mirrodin), but these artifacts can kick some major ass.  Free mana fix with metalcraft, removing permanents for 3 colorless, darksteel creatures, lots of nice equipment artifacts (+0/+3 with Vigilance as a free drop, what?), and Spellbombs return as well.
• Wither + Poison = Infect.  Assuming poison counter rule where 10 poison counters on a player means that player dies still applies, this will be a fun mechanic to build a deck around.  Oh, and don't forget about...
• Proliferate.  Have a creature with a counter of ANY kind on it?  Well it gets another one now!  Ramps up your +-1/+-1 counters, poison counters and Planeswalker counters really quickly.
• Finally, the Planeswalkers.   Elspeth Tirel will be great for white weenie decks, especially white weenie token decks.  Koth will be amazing for your red beatdown and burn decks, especially when you can use his final ability, potentially winning you game by turn 5. And U/W control gets even more powerful with Venser.  Who cares how big your monster is when I can exile it by casting Ornithopter?

If this is just the beginning of what this block will give us players, it should be a fun time for the casual folk and create a ton of buzz/compaints from the MtG community.
