OK, so at one point, I believed that Lava Rushes could max out the damage in 3 turns.
Turn 1:
Play a Ray of Light, Cremate. Play a Minor Phoenix, Cremate. Play three Lava Destroyers.
3 x 7 = 21
You still have a Cremation/Crimson Dragon in hand. You also have 1 Fire Quanta and 2 of each other quanta left. When the turn ends, you gain 1 more Earth Quanta for a total of 3.
Turn 2:
You draw a Crimson Dragon/Cremation (whatever you didn't have before)
You Cremate the Minor Phoenix (without rebirthing) and play the Crimson Dragon.
You Growth all three of the Lava Destroyers.
3 x 9 + 12 = 39 = 60 dmg so far. 40 left
You now have nothing in your hand, 0 Fire Quanta, 1 Earth Quanta, but 3 of any other quanta. After the turn ends you have 2 Earth Quanta.
Turn 3:
You draw and play a Gavel
You growth 2 Golems.
2 x 11 + 9 + 7 + 12 = 50 =110 damage in 3 turns.Quite respectable, no?
I challenge thee to come up with a more damaging 3 turn combo
(it is quite possible, much higher has been
done proven to work, in theory)
PS. Jmdt, Nume, and Kuross. You can't give them the answer
