Looking in gatherer for sideboard choices for my deck i've discovered the card Jester's Cap.
What do you guys think of it against decks like oath?

This thread got me thinking and with mmcgeach advice in mind I built a 4x Thirst Golden Gun deck with Bomberman/Pyrite and Dragon Breath/Emrakul/Blighsteel heavily based on Brian Kelly's list.
Still haven't tested it beyond goldfishing though.

Hi guys

So, i'm thinking in starting playing vintage (there will be a 10-proxy tournament here in my city) and i love this stile of decks.
I'm testing a list VERY similar to the one Islandswamp posted, but now that Thirst for Knowledge got unrestricted i'm thinking of removing the Night's Whispers and adding Thirsts.
What do you guys think?
And what would you guys consider a good sideboard for a field with a lot of URx Delver, Shops, some creature decks like 4c Humans and Bug Fish and without any dredge and storm?

My sideboard for now is this, but i'm not so sure about it:
4 Ingot Chewer
3 Toxic Deluge
3 Grafdigger's Cage
3 Red Elemental Blast
1 Mountain
1 Slaughter Games

Hi Everybody!

My name is Giulianno, I'm from Brazil, I love Commander and Cube and sometimes I play modern and legacy, this month there will be a 10-Proxy Vintage tournament in my city and I've decided to study more of the format so I can do well in it.
I'm still trying to save money so I can buy a vintage deck on mtgo and in the meantime I'm playing some games on Xmage with some friends.
I started magic in 2009 just before the release of Zendikar and I've always loved grixis decks, in modern I play BR Burn, UR Storm and UW Gifts Tron, in legacy i play Goblins, Burn and Ledless Dredge and I'm thinking of building a Grixis Slaver deck for vintage.
My favorite cards are Lightning Bolt, Goblin Guide, Gifts Ungiven, Yawgmoth's Will and Trinket Mage.
