Venomous Dragonfly

Combat with this Insect is a mutual execution: enter the fight and your creature dies after damage, no matter how much toughness it carries. This is one of green's early stabs at the idea later compressed into the single word deathtouch, but the structure is meaningfully different. Deathtouch fires whenever damage connects, including on offense or through trample math; here the kill only resolves through the block-or-be-blocked relationship, which means a defender can refuse the dance entirely and let the 1/1 chip in for a single point each turn. That restriction is the trade-off for stapling a destroy-anything combat effect onto a four-mana body that contributes almost nothing in raw stats. It cannot aim itself; it has to be met in combat, and combat goes both ways. Flying is the pressure that forces the question, pushing damage over ground stalls and tempting a defender to slam a real blocker underneath, at which point both creatures trade and a 1/1 has answered something far larger than itself. The whole creature is built on deterrence: a body so flimsy and an effect so dangerous that the correct play is usually to pretend it isn't there and eat the point.
