haha, kor firewalkers thats funny.
Anyway warren you should look at the B/R version that's actually been winning events. Light black splash with dragonskull summits and lavaclaw reaches for maindeck blightnings and sideboard deathmarks/doomblades to deal with said firewalker.
Don't think mono-RDW has been doing much of anything good lately.
just sleeved up the B/R version myself earlier in the week.
Edit: in regards to the cards though I probably have the quenchable fires and maybe a spare elemental appeal.
