1. If a card is on my Wishlist then I want it. I won't deny trades for cards on my Wishlist, we just need to make it work.

2. I'm always willing to check your list for something.  I play pretty much just EDH so I can find something.

3. I'm willing to overpay with a bunch of small cards to get to your bigger card. I will consider the same in reverse.

4. I value standard a little less since the value isn't as stable so make it worth my while if you want non-standard cards for just my standard wants.

5. If you want/need more value then just say so. It takes effort to put an offer together. I will rarely just say no.  I'll keep countering until we find something we agree on.
