Here's a question regarding Call to the Netherworld and the discard step. Searching MTS and Google turned up no results for this particular interaction.

I've passed through the end step and entered the discard step. My hand contains eight cards, so must discard. A Street Wraith is in the grave. My intention is to discard Call to the Netherworld, exile it via madness, and play it for its madness cost. This is obviously possible. After this, I want to:

1) Cycle the Street Wraith, dredging back a card, and
2) Discard that card as a result of the cleanup step starting over.

It's my understanding that the cleanup step starts over after all of the above abilities resolve, per rule 514.3 and 3a. I would want to discard that dredged card I just got back with Street Wraith when that cleanup step starts over and I discard down to a hand of seven. Is this a chain of events I can make happen?

Thanks! -RT
