Just pulled the Jace, looking to trade it for:

Liliana of the Veil, Tamiyo, or Elspeth, Knight-Errant (1 for 1)

or: a combo of 2

Ajani, Caller of the Pride, Liliana of the Dark Realms, Karn Liberated, Garruk Relentless, Maelstrom Pulse

Depending on which of the above cards, you could throw in one of the B/R, U/B, or G/W Scars Fastlands to offset price difference, or a Spellskite / Ohran Viper / Propaganda.

Thanks for taking a look! I also have a full tradelist if you have any of the above cards and see something you like.
