Redye can seem invincible. But he does live dangerously. Since many of his cards cause himself damage, he can become vulnerable to disabling attacks. If stunned, he may be unable to recover before he can heal back up. Mastery of Redye relies on a keen sense of danger. On a turn he is ready to go all out, it is better to keep the minimal defensive card. But when he is not ready to unleash, a balance of offense and defense is a better approach. Without unleashing, his threat is still limited, being only able to attack once a turn.
