Here is another take at two-color Pirates. I was trying to use Saheeli Rae just because I have a playset, but that didn't work so well. It was worth a try.
This deck IS able to keep casting Pirates, and has enough interactions to continue to deliver damage. Here my opponent gave up. As will all poorly-constructed or unlucjy Red Deck Wins (RDW) decks, if the RDW deck runs out of gas before winning, it just flops.
