Trading my CoS for your Zheart
 

That's right, I'll give you my pre-nerf circlet of shadow, you give me your zlandicar's heart. But, zheart is worth 5+ times what CoS is worth, you might be saying. That's okay, I can wait. You just let me know when this deal starts to sound sane: I'll be here.

6/10, above average troll but fairly unoriginal

Honestly, if you pulled this off 2 months or so ago it might be better, or just hold onto it for a while

I'll trade you my zheart in 2020, I can wait. You just let me know when the time comes: I'll be here.
