I have 4 Tarmogoyfs (2 modern masters 2015 and 2 future sight) that are not listed for trade, though I am willing to trade them for cards of similar value

Generally I'll only trade standard cards with standard cards, modern with modern cards etc. due to the way the prices change, though I'm open to anything.

I try to pick cards of a similar value to what you want (or I might pick higher total value of cards if I'm trading a single expensive card for many of a lesser value).

I'm mostly looking for specific versions of the cards on my want list, particularly the planeswalkers
