Optional SolemnityUse
Solemnity in the main as an offensive weapon. We are playing creatures that would normally have to get -1/-1 counters on them, but, due to
Solemnity, now can't. A 5/5
Ammit Eternal which never gets counters?
Then, depending on the match up, we can transform our deck in the sideboard to one that actively takes advantage of the -1/-1 counter theme and brings in Hapatra,
Obelisk Spider, etc.
