And one day he came to me with a big idea for the set
Coming back from the yard pushes Unstoppable Slasher over the top, though fun fact: If you put a -1/-1 counter or stun counter on it (or any counter, for that matter), then kill it, it wont come back
(Plus, it's only a one-of, so cutting it wouldn't really reduce the deck's cost meaningfully anyway.) The one rare that can be cut is Castle Locthwain, which, as we discussed, is very good and, outside of costing some wildcards, is mostly a free-roll in the deck but not all that important
but with Delve and Convoke, casting it is very easy, and it can even be cast from the graveyard
Looting is especially popular in Rakdos, getting its card draw from discarding to draw a card or paying life for it
A player might also visit their local game store and find dedicated Magic players or entrepreneurs who will buy card lots
