Goblin Girder Gang has received a minor update to its triggered ability. Specifically, the ability will check both as it triggers and as it tries to resolve to see if the result is stored on Goblin Girder Gang. For example, if 3 is not stored on Goblin Girder Gang and you roll two 3s, the ability will trigger twice. If you store the first 3 on it, the second ability won't resolve as it will see that 3 is now stored on Goblin Girder Gang.
