Bogardan Firefiend

A 2/1 body whose real text is the line at the bottom: dying fires a delayed two-damage burst aimed at something across the table. That makes it a trade that refuses to be a clean trade. Block it with a creature and you eat the death trigger; remove it and you can hand its controller a free Shock-on-a-stick pointed at one of your own creatures; let it attack and you take two now while risking the two-for-one later. The design idea is friction on the opponent's decision tree rather than raw stats: it is priced as a beater but plays as a removal spell you cast turns before you cash it in. The damage is mandatory on death and must point at a creature, so it isn't tied strictly to combat; sacrifice the body on your own schedule and you convert it into two damage exactly where you want it, which is the axis that has kept variants of this template alive long after a vanilla 2/1 stopped meaning anything. It is an early articulation of a recurring red common idea (a creature that bites another creature once when it falls), and the shape has been refined under other names since, trading a point of toughness or a point of damage to fit whatever the rest of the body needs to do.
