Hi there! I'm new on this forum, so i'll try to introduce myself. My name is Marco Benifei, i'm from florence, italy, and i'm 23. I play magic since 1996 but i started playing vintage only two years ago. I know that my english is not very good but i'll try to do my best

I want to talk about madness, i love this deck and i played it in every kind of format and i'm still playing it in every kind of format

1)
Let's start with my decklist:
4bazaar of baghdad
4tropical island
1tundra
1island
1forest
1plain
3flooded strand
3windswept health
5mox
1black lotus
4wild mongrel
4basking rootwalla
4circular logic
4force of will
4swords to plowshares
4careful study
4deep analysis
1ancestral recall
1time walk
2life from the loam
4squee goblin nabob
Sideboard:
4hidden gibbon
4naturalize
3energy flux
3roar of the wurm
1balance
I played the deck a lot, i did 5 tournaments in Italy, the smaller with 50 players and the bigger with 370 players, i won 3 and lost 2 in semifinal. I'm not saying it's the best deck ever, but surely it's ok, at least in the italian metagame.
2)
I'll try to analize some cards of the main deck:
bazaar of baghdad
It's a land, you can't counter it, you can't duress it, you draw two extra cards every turn, if it's buried by a wasteland you draw once at the same... simply devasting
Island-forest-plain
Against artifact decks you need them to avoid recursion of wasteland. We play two life from the loam so we could alse keep out the plain, but i'm still happy with this setting.
Life from the loam
I'm trying them... If your opponent has wasteland in the deck you need it, if you opponent doesn't have wasteland is quite useless but the deck is quite bazaar depending so you don't want to risk. Could be one life from the loam main and one in the side? You choise
Careful study
It's really good. In your opening hand you must have a madness activator otherwise you have to mulligan(exceptions are ancestral or blacklotus for a deep), so playing them you have four additional madness activator except to bazaar and wild mongrel. In this way you don't have to mulligan often. You need these card also to draw faster as you can into your bazaar. They are also very important to have blue cards to force of will; usually if you start with bazaar you willn't play careful in that game but you will not discard them because they are the only cards you want to pitch for force of will. I would play six careful study if i could

Deep analysis
You don't have bazaar in your opening hand? Turn one careful and discard deep, turn two deep =5more cards(one of the turn)since the your opening hand. You have bazaar in your hand but you haven't squee? turn one bazar discarding a deep, turn two mox land deep and you can continue to activate your bazaar without discarding key cards. I would play six deep if i could

Squee
It doesn't do nothing...but you need four of them because i must be able to have bazaar in play, i played two tournaments without squee but against decks like gift it was really hard without them
Sol ring
I'm not playing it anymore, because i needed 1 slot for the second life from the loam but i don't now if i did the right choise because with 4deep analysis is really good and also after side if you put in roar of the wurm or if you play against workshop decks...
3)
Sideboard analysis:
Energy flux
You need it only against workshop decks, but if it hit the table you win...
Roar of the wurm:
Against creature decks...6/6 is big

Naturalize
You need it against oath otherwise you lose, you need them against workshop decks and you need it against a lot of other cards like pithing needle, nullrod, jitte and so on...It's a really flexible card for our sideboard.
Hidden gibbon
It's a new entry but i feel so studid to never try it before... It semms ok, but i need testing to decide, other options are orim's chant(against tps and yawgmoth's), or 4duress and one bayou(in that scenario you have to change flooded strand with polluted delta to have 6 fetch lands for bayou)
balance
Often is a useless card but sometime it's the only card that can save you from bad situations
4)
Matchups:
Madness has the particolarity of being a deck that is near to 50/50 in every matchup, in any format, seldomly you are 80/20 or 20/80 so it means that you must be very good playing the deck to take advantage in every matchup. It's not simply to play because drawing a lot of cards and obviously discarding a lot of cards you'll have a lot of choise every turn. The only thing i told you is: learn to play the deck and you'll notice tha's not that bad how it could seem in the beginning.
Sideboarding strategy:
Against workshop decks:
In 4naturalize 3energy flux and 1roar, out squee and logic because they're plenty of wasteland for bazaar so squee often would be useful and the circular logic are bad cards when you aren't able to have a bazaar in play(or tapped out for a tangle wire). All you have to do is take time with force of will, sword and naturalize and finish them with energy flux. After sideboarding you have an huge edge.
Fishlike:
you don't want circular logic, they didn't have bombs in the deck to counter and they're plenty of wasteland, so out. The same for force of will, also because without locig you wouln't have blu cards for it to pitch. In: roar, naturalize(you don't want pithing needle to stay in the board and you can use it also to destroy mishra, nullrod, jitte). Now that i've in my side also gibbons i think i would side for them so i think we could also keep out some squee, depends on how many naturalize we want(we have also two life from the loam that give us cards to discard for bazaar)
Oath:
The first game it's hard but you can count on four naturalize after sideboarding that surely will help you a lot. Honestly when i had duress in the board i used to keep out wild mongrel, basking rootwalla, life from the loam and the plain(depends if they play wasteland) for duress, roar and naturalize and playing the game like a control deck, taking advantage with bazaar and don't letting oath being activated by creatures and when i was sure to be in control winning casting a roar from the grave; but now that i run gibbons instead of duress probably the plan will change and we'll have to try rushing them with gibbons wild mongrell and rootwalla, siding out life from the loam the plain and the swords, but i'm not sure it would be the best strategy, i've to test it before.
Tps, gift, pitchlong:
It's not easy to sideboard against these decks because it depends a lot if they play dark confidant or not(to decide how many swords to side out), it depends also if they run pithing needle in the side(naturalize). Against gift is a lot easyer because the are slower then tps and pitchlong or similar decks. Surely gibbons put pressure on them and if they run dark confidant it's a good thing; if they wouldn't play dark confidant i think that keeping out the white from the deck and sideboarding for black with bayou and the duress would be much better, because it's true that madness it's an aggro-control but in vintage i like to play it more control than possible because creatures often are too slow and it would be better have a contrast.
I'm going to stop now, i hope you enjoy the article and that you'll help me to test the deck. Every kind of reply is welcome, obviously also criticism.
Have nice games!
Marco
