After realizing that I have the complete landbase, I've decided I might as well put together Legacy Goblins. The big cards I still need are:

2x Goblin Piledriver
2x Goblin Lackey
2x Aether Vial

and to a certain extent:

2x Thalia
4x Angel of Despair
3x Pyrokinesis

I've put the complete list of things I need in my wantlist, so feel free to take a look. I'm also very flexible when it comes to trading, so feel free to add/subtract stuff... I can usually find something I'm interested in.
