Rev 26: BUTT-HEAD's ram is priced into the blow, so STRENGTH, AMPLIFY, and the counters weigh it (KWUZ)

Ramses cast STRENGTH, then an amplified BUTT-HEAD three squares off, and
the goat dealt three: the ram was applied in onResolved, past the pipe
that doubles, soaks, and adds. Older games keep the bare distance.
