Which would be a better fit in a very aggressive rakdos deck; {vexing devil},{stormkirk noble}, or {rakdos shred-freak}?
{Vexing Devil}, he's a giant {Lightning Bolt}, and if he sticks, he's pretty huge, where as the Noble has to connect, and the Shred Freak is pretty small for a 2 drop, although it all depends on the curve. For aggression, Devil all the way.
Just do what I did and run all three😝, seriously though it depends on what you are facing. Shred freak races damage, devil is 4 damage until they can either deal with it or if it sticks forces blocks they don't want
Noble is great with human heavy builds and I have seen him as the important 1 drop vampire
