Undeclared orders

[TracerBullet]

Simple question-

An opponent controls both a Smokestack and a Tangle Wire.  During my upkeep, he does not declare what order their abilities go on the stack.


Am I allowed to tap my permenants before I sacrifice them?

He HAS to declare their order.  You can't continue until he does so.

You can always ask him leading questions, like "do you want to do anything before I resolve Tange Wire?"
