Confusion on sacrificing

[Marcusdigio]

Lets take  {Corpse Traders} and   {Barter in Blood} as examples. And maybe also  {Blood Artist}
Is there a link to an article I can read for clarification on sacrificing? Lets say my opponent plays barter in blood. How do I go about feeding blood artist the sacrifice without playing an additional sacrifice? I think my confusion on this came cuz I'm now on mtgonline and the way I've played with cards and the order of clicking is what's confusing me. In order for it to work I have to do it in a certain order with the whole stack concept. Can someone help me with this? I'm sorry I probably am not even phrasing my question well.

What do you mean by feed the blood artist the sacrifice without playing another sacrifice? I'll be glad to help, but I'm not sure I quite understand the scenario.

Lets say I have  a {blood artist}  {Corpse Traders} and zombie token in play. Can I use the zombie token to satisfy both? If so how?

Are you looking to satisfy the barter in blood and the corpse traders, or the blood artist and corpse traders? If you sac the token with the corpse traders, blood artist will go off as well.

New scenario. Just these two.

If you sac the token for {Corpse Traders} ability, {Blood Artist} will go off too, since a creature died.

When I am playing mtgonline it keeps making me sacrifice another creature.  I don't know how to make the one sacrifice satisfy all of them.

 {Blood Artist} isn't looking for a sacrifice. All it is looking for is something to die. When that happens blood artist sees it and triggers his ability.

1 sacrifice for  {Corpse Traders} = reveal & discard and the  {Blood Artist}s +1 -1 life change.

What about  {Corpse Traders} and   {Barter in Blood} and two zombie tokens in play. How would I make that work so I only have to sacrifice the tokens and get to use the sacrifices I satisfy both the barter and the corpse?

This you cannot do. First off, once a creature is sacrificed, it's done. You aren't able to sac it for barter and then sac the same one for corpse traders. Also, corpse traders ability can only be played at sorcery speed, so you can't respond to the barter in blood.
