'"Whenever Summon" effects (such as from Pack Leader and Mama Bear) will be cast twice on the extra copies.'
Looks like we may need to restructure our Khadgar implementation. Currently we have Khadgar summoning extra plain copies of minions, but it looks like it actually summons buffed copies, i.e. Khadgar's multiplier is applied after buffs, not before. For example playing an Alley Cat with Khadgar and Mama Bear will generate a 5/5 and a 9/9 Tabby Cat, because Khadgar copied the already buffed first Tabby Cat.
