Breaching Hippocamp card art
Breaching Hippocamp enters the battlefield and untaps another creature you control — that's the whole engine, and it's enough to go infinite with Kiki-Jiki, Mirror Breaker. Four mana on a 2/3 body is a steep rate for fair play, so this card earns its slot exactly one way: as a combo piece.

Breaching Hippocamp is a pauper-legal common, which is the only non-Commander format where it sees any meaningful discussion — untap triggers on a body have niche applications in creature-based combo shells there. In Legacy, Modern, and Pioneer the four-mana cost price tag prices it out entirely; faster, cheaper untap effects exist at every turn. Commander is its natural home, where the singleton rule makes redundant combo pieces worth including and the slower pace lets a four-drop resolve without immediately losing the game.
