American Control

You're running at least 1 too many 3-mana hard counters.
Boros Charm doesn't fit as much as you might want it to.
Aetherling needs a friend?
Ral Zarek is an burn-style izzet planeswalker, and this is supposed to be a control deck?
Gothy pointed out that Jace, Architect of Thought is a control-oriented planeswalker.
Mizzium Mortars makes me confused alongside a stack of Supreme Verdicts. What's your reasoning?

The idea is clean up / counter everthing until to enter Aetherling or Espelth. Who would be a good friend for Aetherling? About Boros Charm, there are some options that could work: indestructible for my tokens for the Supreme, Double Strike for Aetherling to finish the game or copy in the ultimate of Chandra. About Jace, I agree, but the only problem is that I don't have it... (here in Brazil Mtgis not so ship). Thanks for the comments!

Running 1 of win conditions is asking for your combos to be shut down.
Acquiring a Boros Charm in conjuction with Aetherling and tokens is very unlikely when you only run a total of 3 of them.
Expecting Chandra to get there on her own without some defense is quite unlikely without some tougher instant speed removal.

I don't see any real answers to green and red aggro decks in your choices apart from Verdicts after taking significant damage.

yep. That's Ral Zarek's biggest problem. He's in a block with one of the best planeswalkers ever to haunt a format. And they occupy the same slot.

hey rafael.angelo what are the Boros Charms for specifically? the indestructible? cause keeping them around just to give Aetherling double strike is iffy. If you're using them for the indestructibility you're protecting your permanents from targeted spells usually... Wouldn't you be better off with another counterspell?

Hey kmk888, that are my ideas for Boros Charm: indestructible for my tokens for the Supreme, Double Strike for Aetherling to finish the game or copy in the ultimate of Chandra. What do you think? What would you use in the plane of that? Thanks!

Okay I see the Chandra, and that whole thing is kinda cool. But 3 is too many. You know what I would do? -1 Boros Charm +1 Assemble the Legion. Then put 2 Assemble the Legion in the sideboard and you can really punish certain decks. Nice brew though.

American is what most people who don't know about the -volver's call the RedWhiteBlue decks. There's a lot of different ways to interpret it all.
Each pair(2) of colors has a guild.
5 of the 10 trinity(3) are Jund, Grixis, Naya, Esper, Bant. The other 5 of the trinity's are called by many many names. The apocolypse set had 5 volver cards; Ana(green blue black), Ceta(red green blue), Dega(red white black), Necra(green white black), and Raka(red white blue). These 5 are also called by the name of their respective dragons by some and ugly names like Junk, American, RUG, BUG, etc.
The 5 4-colors are usually distinguished by the Nephilim names.
5-color tends to be called 'five color' or things like Maelstrom or Conflux.

I know about colour-combination names, but why would this one in particular be called american?

Sorry man, I didn't undestand your question. As chaoslord00 answerd, it is because RedWhiteBlue Deck.
