Bug with Syndicate Trafficker.
She was taken from me with Welcome to the Fold.
The whole battle, opponents (folded) Syndicate Trafficker would get +2/+2 whenever one of my Supports were destroyed instead of the opponents supports.
Syndicate Trafficker says
When a support is Destroyed from the board, this creature gets +2/+2.
It doesn’t say support you control, any support will do.
Thus it should get buffed even when you control it and one of your opponent’s supports is destroyed.
Yup. That’s how he works. Always makes me happy when I see him out and my opponent plays Tamiyo’s Journal for exactly that reason.
