I decided to get into legacy with my own cards about a month before gp new jersy. Unfourtinately I did not attend. i wanted to bring a combo deck based around ugin's nexus. here is a rough draft of the deck it basicly uses a nexus to take extra turns to kill your opponent with myr batlesphere

4 shivan reef
4 island
4 seat of the synod
3 great furnace
1 phyrexia's core
4 ancient tomb
spells
4 thoughtcast
4 intuition
4 force of will
4 careful study
4 ugins nexus
2 daretti, scrap savant
4 izzet signet
2 flusterstorm

dudes
4 goblin welder
4 myr battlesphere
1 sundering titan
2 wurmcoil engine
i would love to hear feedback on how to turn this into a real welder deck. If I have to cut some of the nexus' thats fine 4 is probably overkill.
