Iron Valiant ex has a storied competitive history, primarily due to its Tachyon Bits ability, which allows you to place damage counters on the opponents Pokmon just by moving Iron Valiant into the Active Spot
A lot of times, just the threat of making them indestructible is good enough to make opponents let them through, especially with Goreclaw giving a size boost and trample to your larger creatures

Sometimes countering the first swords on our big creature wins the game
EDIT: This apparently also applies to the SM1+ set
