So it seems the only viable MO deck is an Overwhelming Hunger mixmatch of gold deathwish units, the Yghern Ozzrel package, some Wild Hunt and of course some thrive, namely Bruxa and Endrega larvae. They literally have no archetype gameplay that's competitive enough.
Why?
The vast majority of their Bronzes are whack.
Now, imagine if:
Ice Giant was something like 5 power - if Frost is present on the board, boost self by 1.
Vran was - whenever a unit is destroyed on your turn, or when an opponent destroys one of your units, boost self by 1. Alternatively, could simply make it 4 prov
Wild Hunt Hound was 4 prov.
Celaeno Harpy was 4 prov, or Consume two units (i.e. to help with tempo to proc all the DW you may have lying about, but then can backfire if you only have 1 and there are cards you don't want consumed). Or maybe 3 power and consume a unit - if the unit consumed is harpy egg, spawn another one.
Ice Troll was if you control the same or fewer. This would open it up a bit. Could make it start at 4 if this was too strong.
Cyclops was 5 power or 4 prov and not row locked
Maerolorn was 4 Prov
Archespore was deal 3 damage on DW
Werewolf was boost self by 1 whenever you play a beast.
