Which card did behave improperly ?
Kolaghan, the Storm's Fury

Which update are you using?(date,name)Which type(Duel,Gauntlet,Sealed Deck)
BfZ, Duel

What exactly should be the correct behavior/interaction ?
When multiple dragons controlled by Kolaghan, the Storm's Fury's controller attack, Kolaghan's triggered ability triggers once for each attacking dragon.

Are any other cards possibly affected by this bug ?
-

The same bug affects all five legendary dragons in Fate Reforged - both halves of declare_attackers_trigger() always need to be passed the same mode, or the world explodes. That's why I wrote it as one function; if you can't muck about with its internals this kind of bug can't happen. Premature optimization again. Fixed in 3010170.

Also split Kolaghan, the Storm's Fury's two separate effects into separate effect text, and merged both its and Silumgar, the Drifting Death's pump effects, in the same commit.
