if they both got the deathrattle from the same minion wouldn't they have "each gain[ed] a Deathrattle from your minions that died this game."
i agree with OP that, since they are two different minions, it would make plenty o' sense if they had they're own pool to grab from.
its not the same as raise dead or Da Undahtakahhahah.
it is also true that it could clearly be either, and pontificating could be pedantic which, in the words of M. Tyson, would be "ludicrous!"
I don't know, dude, I just read the card the way it currently works all the time. Maybe it has to do with the fact I'm not a native English speaker and only see it from my own perspective.
