Here is a good working raid strategy for Haast Maximus.
As usual, this must be done exactly as shown. Tuoromoloch’s moves are vital to be done exactly as shown. It is vital Tuoromoloch do speed the 1st turn of round 3 so Diorajasaur can fire off Instant Invincibility before Haast does instant 2X which will kill the raid. If Tourmoloch does not do Group Superiority the 2nd turn of round 3, the Thors will need to do Instant Charge to finish, round 3, turn 3. Tuoromoloch may need to have it’s health boosted if it gets killed in round 2, turn 2.
Follow exactly and you can do this in 7 turns.
