Back for More

In Commander, Back for More earns its slot by doubling as interaction and reanimation on the same card — flashing it in to steal a freshly killed threat or surprise-block an attacker while getting a body back is exactly the kind of flexibility that six mana needs to justify in a singleton format. Competitive Commander tables will almost always prefer cheaper, faster reanimation, but at casual and mid-power tables the instant speed alone sets Back for More apart from sorcery-speed alternatives. In Legacy, Modern, and Pioneer it's legal but rarely worth the slot — dedicated reanimator shells have more efficient lines, and the six-mana ceiling is steep in formats where games often end before turn five or six. Oathbreaker follows the same logic as Commander: playable, appreciated most in slower grind-oriented builds.
