I would say this is possibly game-breaking. So in Arena my Koolasuchus Gen 2 was fighting a Velociraptor. I used distracting strike as their pounce was on cooldown and I knew it was coming next turn. Then I used instant cripple. When the velociraptor used Pounce, my Koolasuchus was HEALED by the attack. To make matters worse after my Koolasuchus “died” to another dino it didn’t actually die. It’s health read 0 but it still did an attack. It took an extra attack after it’s health read 0 for it to die. My apologies to my opponent who had to deal with the unfairness.
