Two Thors with at least 2600 or more attack could do it. Both use Group Shattering Impact, and the Entelodon is definitely down while the Gorgosaurus might survive, but barely.
Have a very good Diorajasaur use The Priority Group Shield Taunt on turn 1, and the Thors get about only 800 damage on the Counter attack, and the Gorgosaurus definitely dies from Dio’s counterattack
Only thing is, there needs to be a VERY powerful Touramoloch to heal. It uses it’s Priority acceleration to make sure the Thors kill the Minions on turn 1, then Dio throws up the Group Shield, and Thors do Group Shattering Impact.
Turn 1: Diorajasaur Group Shields, Touramoloch Group Accels, Thors use GSI
Turn 2, Touramoloch uses Group Heal, one of the Thors uses Instant Charge, the other uses DSI, Diorajasaur uses Rampage
Turn 3: Touramoloch uses it’s Priority Heal (unless Hadro was stunned on turn 2), the other Thor uses its Instant Charge while the first Thor uses DSI, and Diorajasaur uses its Strike.
Turn 4: Diorajasaur shields, Touramoloch uses it’s Priority Heal) one Thor uses it’s DSI while the other just uses it’s Strike.
Rinse and repeat for each round?
Edit: This of course depends on the Thors stunning Hadros. If in dire straits, the Diorajasaur should use IIT to make sure Hadros keeps attacking only Diorajasaur.
