Strength gets its grip: tear a treasure from a wizard's arms

The card's second power was never built. New tearTreasure command: with
STRENGTH on you, in the same square as a carrier, the tear spends your
attack; the victim keeps the treasure only on a D4 roll of 1. Per the
FAQ it is not a pickup (your turn's actions continue), and full or
weakened arms tear it loose onto the floor instead. A torn treasure's
warded owner gets their window, blind grabs flail like blind punches,
and the automatons wrestle too. A new command breaks no stored ledger,
so live games gain the grip at once.
