{Howl of the Horde} {Shrapnel Blast}
Do I need to sac 3 artifacts?
So attack with {scuttling doom engine}, say it goes through, sac it to shrap, then howl with raid for a total of 27 damage that turn. That's a little scary
And cast the {howl of the horde} with a {pyromancer's goggles}
Why not just play modern storm? Or cheerios
Because this this a standard viable combo.
Even 15 for 5 isn't bad.
