Though i also recommend starting with Lotus, this is the order in which i acquired power:
Ruby > Recall > Sapphire > Time Walk > Lotus > Emerald > Jet > tbc..... still missing Pearl and Twister.
If you got a good offer (like i did) you are good to buy other pieces of power before Lotus 
@ajfirecracker 9th Place at Eternal Weekend Europe (October BOM) was a Pitch Dredge List with Amalgams. I won against him in round 5 but unfortunately we both didn't made Top 8 (me at 12th, he at 9th) 
Metallurgic Summonings

Enchantment
Whenever you cast an instant or sorcery spell, create an X/X colorless Construct artifact creature token, where X is that spell's converted mana cost.
3UU, Exile Metallurgic Summonings: Return all instant and sorcery cards from your graveyard to your hand. Activate this ability only if you control six or more artifacts.
For me this card is vintage playable. In a big blue deck it should be really fast on the board and will give you an army of Constructs just for playing other spells. Draw two cards for zero Mana and get a 5/5? Sure 
And if you don't need those pesky creatures anymore you can just get you're time walks and recalls back.
Can´t wait to play this guy. But Conspiracy isn't released on MtGO, right? Due to the lack of players in my area, i play very rarely paper vintage
Hi folks, my name is Christian. I play in the european time zone and my name on mtgo is the same as here: Deibler
Congrats to Collecter and the rest of the Top 8.
As ChubbyRain (great work btw) mentioned i went 5-2 with Jeskai Mentor where both of my losses coming from white eldrazi and most of those games (1-4) weren't even close. Seems like the Eldrazi menace has finally arrived in Vintage.
@Islandswamp Thanks for the input. Looking forward i think adding 1-2 Mentors is the way to go. Not only diversifying threats but also just adding them is important. As i'm often controlling the opponent but have no threats to end the game.
@Islandswamp Nice article. Maybe i should play the Forest Main instead of LoA. The first Versions of this Deck had more green spells including Fastbond ( +4th Gush) and Sylvan Library.
