As a result of us getting the rules wrong (namely what does and does not count as spells), This Troper got quite thoroughly rushed in a MagicTheGathering game by my brother's use of the Hostility card, resulting in exponentially growing numbers of Elemental Shaman tokens. The final result was a rush of ''7,289,897'' tokens, plus the other cards he had on the field, resulting in an overkill of ''21,869,695'' damage points.

I once joked (at an independent pet food supply place in a major city near mine) about raising a really big number of chihuahuas as guard dogs just to invoke this trope.
