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)?
- 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.
