I did what @Andy_wan_kenobi suggested, killing the first one right off and trying to build up reserves.
If the AI attacks me and I know they saved 1 action point, I would do 2 attack. Then sometimes the new raptor that comes in doesn’t attack, so instead of guessing or wasting action points/health I use shields. If the raptor doesn’t attack, they usually use 2 shield and 2 reserve so I would do 4-5 shields depending on action points to minimize damage taken.
The AI will usually attack with 5-6 attacks after that, then you don’t need to guess and know how much attacks to take out the raptor without wasting action points. I usually built up 8 action points during the 2nd raptor battle. Then I would use 4 Reserve, 2 Shield, 2 Attack. I get 8 action points again next turn and would have killed the raptor and minimize any incoming damage if the raptor attacks next turn.
This is probably good until 4-5 Raptors remaining, because it gets harder and takes 3 Attacks to kill a raptor. But, this is where I lose my first dino but you should be good at this point.
I put my strongest Lv10 VIP Amphibian last (527 ATK), because this lets me finish the last 2 raptors with 2 attacks, instead of 3. The first 2 are the same strength, 405-413 ATK.
Hope that helps, you still have time to finish.
