Text (GP): 6/7, Trample. ; Whenever ~this~ deals combat damage to a player, put a +1/+1 counter on each creature you control.
The ability won't save your creatures that were dealt lethal damage in combat. Those creatures will be sent to your graveyard before they would get a counter. [Guildpact FAQ 2005/12/22] This is because the ability is triggered and goes on the stack only after you remove the creatures that died during combat. So only the ones that live get counters.
