Schools of Magic: Commander; Red

Finally we're at my favorite color! I haven't looked through the cards yet, but I suspect that we'll find a higher percentage of Chaos magic here than we did in Magic 2011.

Red

Elemental: Red Elemental magic includes fire, lightning and earth.

Emotion: The color of passion, Red has domain over all emotions.

Chaos: Red loves chaos, and this school includes all those spells that deal with luck.

Akroma, Angel of Fury: A weird alternate universe of one of the most popular angels ever created, this version of Akroma is part of the Elemental school despite her name.
Anger: An excellent example of Emotion magic.
Avatar of Fury: Much like Akroma, this spell is part of the Elemental school despite the name.
Avatar of Slaughter: Our first new Red spell is also an awesome example of a powerful Emotion creature.
Breath of Darigaaz: Firebreathing is almost always an Elemental effect, and this spell channels a powerful dragon's fiery breath.
Chain Reaction: This is a lightning spell, meaning it is part of the Elemental school.
Chaos Warp: Chaos is in the name, and this is new spell is a great example of what happens when you introduce a bit of Chaos magic to the battlefield.
Chartooth Cougar: Firebreathing means this is Elemental magic!
Cleansing Beam: A powerful example of Elemental magic.
Comet Storm: Another powerful example of Elemental magic.
Death by Dragons: Oh man, I love everything about this card. A new spell, this is somewhat hard to place because dragons aren't attached to any school in particular. In this case I think I'll go with Chaos because that is definitely what this will cause.
Disaster Radius: A nice, devastating example of Elemental magic.
Dragon Whelp: Aw, it's a cute little dragon that can breathe fire! That means it's Elemental magic.
Earthquake: Once again, Elemental magic. This is almost as tiring as listing all the Blue Mind magic.
Faultgrinder: This strange ladybug/sea turtle/centipede hybrid is a pure Elemental spell.
Flametongue Kavu: And again, this is Elemental.
Furnace Whelp: Elemental.
Goblin Cadets: Finally, a non-elemental spell! This is a rare low-mana Chaos spell.
Insurrection: This is the ultimate Emotion spell.
Lash Out: More Elemental magic.
Magmatic Force: The fact that this new spell is Elemental doesn't dampen my love of it at all. It's a continuation of the cycle started by Verdant Force and now including Celestial Force, this might be my favorite new card in Commander.
Mana-Charged Dragon: This new spell has an interesting variation of firebreathing, making it Elemental magic.
Oni of Wild Places: A tricky spell to place, I think the combination of Haste and its bounce ability makes it Emotion magic.
Punishing Fire: Elemental with a bit of Chaos mixed in.
Pyrohemia: A nasty and fun example of Elemental magic.
Rapacious One: It is so hungry that it tramples past all in its way! I'd place this in the Emotion school.
Ruination: Oh no, this Elemental spell is destroying Easter Island!
Spitebellows: Despite the fact that direct damage is normally Elemental, this creature's name makes me put it in the Emotion school.
Stranglehold: This new spell is hard to place until you read the flavor text. At that point it becomes clear that this is Emotion magic.
Sulfurous Blast: Once again, this is Elemental magic.
Vow of Lightning: This grants Elemental abilities while adding an Emotion effect that prevents the creature from attacking you.
Wild Ricochet: It changes how another spell works, meaning this is Chaos magic.
