Brontolasmus for starter, and Erlidom for backup.

Without Boost, Procerathomimus can't solo Deinocheirus, some trap will be needed, like Deceleration.
Brontolasmus is good starter since I already seen Ourano and Deino as opening, and only once on Dilo. DR + RA can maximize the damage, Ourano will remain 2236 HP after this combo.
(But I don't know what AI will use because Ouranosaurus was not opening)
Draco Gen 2 for changing member, plus 40% Hp attack as Instant attack.

First of all, I tested on first creature AI sent: If Ouranosaurus first, my next creature will be Erlidom, for enough power to kick it.
After Deino took down Rhino, I sent Proce to blow it with simple attack, then Ourano came.
ES for better benefit (keep dodging to extend survive turns), and I didn't count that AI using IAR, so I went with backup.

For Speed reason, AI didn't send Dilo as second creature, I feel a little disappoint that can't do easy takedown.
