Rather, its a strategy decision
The tradeoff is that an opponent gains control of the Chimera and poses the same problem for you
In Commander, you begin the game at 40 life
Cards like Mystical Tutor, Solve the Equation, and Spellseeker ensure you have the perfect answer at the perfect time
Making it so that it cant be countered is crucial, since youre investing a whopping eight mana to cast it, but your opponents can still interact with it a bit by killing whatever creature you have with the highest toughness
Theres no overarching strategy or theme that would use this best, but its still a super sweet card that many different casual Commander decks could put to use, and I hope to try it sometime after release
