Esper Zombies!
The last set Bloomburrow has the nice surprise of Valgavoth, harrower of souls. He made everything and anything that did constant plinko pings and was Red and or Black as good as gold. The precon for Aetherdrift with Temnet, Nakamun’s Will is doing the same with anything and everything Esper that goes with Zombies.
Particularly: Anything with a madness or connive effect and or graveyard recursion. Varina has blown from 50cents to $15, unfulfilled desires, The Scarab God, rooftop storm, …. All sure to make an undead blast.

Trading Magic: the Gathering Cards:
I try to keep a current a list of cards I am interested in posted up on deckbox.org You can find me on there with this link Deckbox.org . It has a great organization system with links all kinds of formats for simple cataloging.
Mail trading is what it is these days and in person trading at local conventions or shops is likely the easier way to make arrangements. Regardless the click and add and bulk entry to copy and paste decks or trade lists is convenient.
Also archidekt has more great tools and I’ll fill in some details for that here later
