The attack stats definitely need to be around what they are posted below.
I think it only works if Thor and Tenonto CRIT, but that might not necessarily be the case. Worth a shot either way.
Edit: I know for a fact it works, my alliance and I did it without any issues; in fact I thought we might have been doing too much damage
Also, the Thor gets offed on Turn 5, but that won’t be an issue, since Mortem will have about 5k or less health by then.
