I have several sets of Vanguard Set 1 cards. They include the following:

Ertai
Gerrard
Karn
Maraxus
Mirri
Sisay
Squee
Tahngarth

Each set runs about $15 on tcgmid, I'd be looking for around $10 in trade. If anyone is interested, shoot me a trade offer. I could trade for other things that are not on my wants list.
