Notes
This combo works by taking advantage of the fact that you can activate mana abilities during the declared activation of an activated ability. This allows you to delay putting the Trawler and Retriever triggers on the stack (and selecting their targets) until all permanents you need to target are in the graveyard. For more information, please see rules 605.3, 602.2b, and 601.2g.
