The models with Relish in Blood can choose not to grow after getting the Token, so we can stack 2 tokens on a terror tot, and then get Ancient Ritual again in turn 2. With 3 Tot, 2 Shaman and enough corpses(provided by Black Blood Shaman or Noxious or Hayreddin). Nekima2 can grow 3 Sz 3 Nephilims in turn 2.
Turn 1 with 7 tokens (6 corpses needed):
4 Grim Feast(including 1 tot summoned this turn)
2 Ancient Ritual
1 Only the Strong Survie (with Vicious Vitality)
Two tots should hold the tokens for turn 2.
Ideally we should have a Young Nephilim(we need one tot to grow because of the model limt of Terror Tot) with 0 token. 2 tots with 2 tokens and 1 tot with 1 token.
I've practiced this opening for several times, it is not hard, but it really needs some practice. Remember to use Bloody Banner if able.
Plan carefully for each activation, the sequence is not fixed. Sometimes we need Hayreddin to use stones and sometimes 2 Black Blood Shaman can drop 4 corpses.
And be careful with the 4HP Young Nephilim, without Protected, it is just one shot away from death.
Turn 2 with 8 tokens (7 corpses needed, ideally)
The Young Nephilim with 0 token can get 2 tokens by Grim Feast and Only the Strong Survie (with Vicious Vitality).
2 tots with 2 tokens can get 2 tokens for each by Ancient Ritual (remember to grow after the Ancient Ritual) and Grim Feast. Pay attention to the activations, because the Ancient Ritual need to be applied before the Grim Feast.
1 tots with 1 token can get 1 token by Grim Feast.
1 tot summoned this turn can get 1 token by Grim Feast.
The first 7HP Mature will be killed in late turn 2 in most cases, so we can grow the second and the third one to maintain the pressure.
Or we can grow a Cavern if we were lucky.
I've played this list about 3-4 times. The turn 2 requires a lot of improvisation without disrupting the buff chain.
What do you think of this idea?
