Resolved Invasion of Ikoria - Zilortha(reverse side) bug, it was exiled and returned, came back on my side, I couldn't get the creature from it anymore.

[MarkChalice]

During a long and involved game, I cast Invasion of Ikoria, and then cast the reverse side, Zilortha.

My opp cast seal from existence on Zilortha.

I cast seal from existence on my opp seal from existence.

The battle returned to play, still owned by me and said owned by me, but was on my side of the battlefield. So I couldn't attack it to get Zilortha back again.
