destroyed or sacrificed eh? If destroyed, what would prompt your opponent to destroy it? The opponent must benefit somehow. If sacrifice, whats to separate this from a spell besides 1 turn delay and that your opponent could counter?
This raises an interesting point.
Maybe the seals will activate when destroyed, but they don't have the "destroy" or "sacrifice" ability on its own, so you have to find a way to destroy them.
But the problem is only few elements have CC, so this makes things a little more complicated.
Maybe they can all have a trigger that make them destroy... i don't know, i'll give a try:
Mortiferous Seal
If destroyed, add 10 poison counter to your opponent.
Destroyed if you have more than 30
.
This is only an example, of course. You can destroy it with CC or you can wait for the trigger.
I choose to use excess
for the trigger because when you use Soul Catchers there is no use for all that quanta!
