I control one Synod Sanctum, exile some permanents with it, and then my opponent destroys it without me being able to use its returning ability.
If I later on draw another Synod Sanctum, can I return to the battlefield the cards exiled by the first one?
The wording is:
Return all cards exiled with Synod Sanctum to the battlefield under your control.
What if I get the same Synod Sanctum back with Trash for Treasure? It's the same physical card back on the battlefield. Does the game consider it's the same instance or a different one?
