Cinder Elemental was a top Mercadian masques limited pick, because you
could play it on your 4th turn, and kill it for 4 or more the next turn. Same
for Type 2. Cinder Elemental works great with Dark Ritual. Play it your 2nd
turn, wait for more lands, Ritual again for killer damage. Not bad against
Stompy or the like. Here's a deck playtested and it works pretty well:

Cinder

10 Swamp
10 Mountain
3 Urborg Volcano

3 Blazing Specter
3 Cinder Elemental
4 Raging Goblin
4 Blood Pet

4 Dark Ritual
4 Terminate
3 Urza's Rage
4 Seal of Fire
2 Soul Feast
4 Duress
2 Haunted Crossroads

    Notice the crossroads. Since most B/R decks either are mana-swarmed or
mana-less, this card takes care of both. Most useful for any creature in this
deck. Take care of counters with Duress and burn a little extra with Seal of
Fire and the Rage. There's a bit about Haunted Crossroads in a good deck too
;) .
