Hi, I'm thinking of a similar deck and I think a good idea is to include
Hero of Precinct One to get a token whenever you cast a multicolored spell, which makes
Heroic Reinforcements, another multicolored spell, great (you get three tokens instead of two, which is incredible). Also, I think you should make the deck a bit less clunky: Teysa has obvious synergy with
Afterlife, while Judith doesn't since the second effect doesn't trigger with creature tokens. I think you should focus on either one or the other, adding more actual creatures if you choose Judith or play more of that artifact if you choose Teysa (I didn't notice the spirits get pumped!). Finally, I think playing
Kaya's Wrath in such a creature heavy deck (even if many creatures have
afterlife) is bit counterproductive, but not obviously bad. Just think a bit if it is the correct choice! Nice idea though, I have a very similar one as I said.
