It’s a bug. Sion is reviving through isolate in arena. A lot of players seeing it.

Sion and isolate is this:
"can't attack or gain positive effects out of turn"
Revive is a positive effect.

Isolate only prevents revive if he dies out of turn.
If it is his turn and he dies from dots or counter attacks basically anything that can kill him during his turn he can revive.

DT Deathmark has been broke and all over the place forever. If you check the mechanics on swgoh.gg deathmark is supposed to apply revive immunity.

Deathmark's ability description is a bit incomplete compared to how it was described originally in raids. We need to update the ability description to show it prevents revives as seen below. The patch fixed the Nightsisters (besides Zombie) being able to revive even if deathmarked.

The only revive that can't be stopped is zombie unique. So if a character killed with deathmark is reviving than deathmark is still bugged.

The Dev's will most likely not do anything about it reported here as it seems all bug reports need to go thru answers.ea.com. Good luck
