1. Bloodpyre Elemental
This is a solid common. You have the option to attack or sacrifice to deal damage to your opponent.
If you cant read the text this card basically says deal X damage to target creature or player. If deal damage to a creature it cant be regenerated and if it dies this turn you exile it instead.
3. Cone of Flame
I can't decide if I like Cone of Flame or Disintegrate more. This card allows you to deal 1 damage to target creature or player, deal 2 damage to target creature or player, and deal 3 damage to target creature or player.
4. Skarrgan Firebird
Will Wizards bring back Bloodthirst? I would love a 6/6 flyer that you can return to your hand from your graveyard for only 3 mana.
5. Kalonian Tusker
Kalonian Tusker is one of those in-between cards, a little to good to be common but not good enough to be uncommon.
