I asked a general question about double sacrifice bonus, but thought it better to ask a specific question. If a creature has a "Sacrifice this creature for X" ability, can you sacrifice it for that ability and satisfy the requirement of the Eldrazi Monument with the same sacrifice (assuming it is done during the upkeep)?
Oracle Text:
- Creatures you control get +1/+1, have flying, and are indestructible.
- At the beginning of your upkeep, sacrifice a creature. If you can't, sacrifice Eldrazi Monument.
If you can't...
they will sayIf no creature was sacrificed in this way...
