Shadowless Shadow

Riffing off of Stormblessed's Primalless Primal [Top 50 Diamond 3 Clickbait], Shadow is slightly more broken than primal is. Sure, we don't have Maveloft Huntress, but Shadow has its own vicious stranger top end and a more flexible set of 2-cost cards that can give you longevity against those nasty control decks.
Oh yeah, did we mention Cast Iron Furnace?

P.S. Dizo's Office is yet another site in a deck filled with them, but there just isn't a better top end for Shadowless Shadow.

1/13 Update: I think Shoaldredger is just too good to leave out since it helps with Furnace and provides extra punch and sometimes a big, cheap fatty.
