Extremely high numbers for a 1-Cost card, and in the toughest fights in the game you'll often be piloting a deck where Osty only has 1 or 2 Hitpoints when you sacrifice him anyway.
Excellent card for the early game as it can solve many encounters on its own. Worth an early upgrade because both effects scale.
