Let’s take a quick rundown of what Wrath of God’s loss today means:

White cards extinct

Wrath was the last white card. The finalists will decide whether it’s red or green on top.

Sorcery cards extinct

Wrath was also the last sorcery. The finalists are a creature and an instant.

Converted mana cost 4

Wrath of God was the last remaining 4-cost card. This does mean we know the CMC of our winner - it’s 1 either way.
