These are cards that have spiked up in value over the past year or so because of the popularity of Old School and the changing collectible marketplace
X=1 is pretty bad, X=2 is serviceable, and anything from X=3 and up seems actively strong
Rating: 6/10 A long time ago, Merfolk Looter was a very powerful Limited card

In my opinion, the strongest things you can do in Mono Red are: "Glass cannon" decks that either quickly pop off and win before opponents can stabilize, like Storm, Krenko, Purphoros, Slicer Crushing nonbasic lands, aka defeating a large chunk of players with a single Blood Moon The problem with these two strengths is that they aren't always the right pick for casual tables
