New red burn
Here is another red deck, a very easy deck, very famous, very boring to play against, and with a high win rate.
Everything here is made to damage your opponent while you are in combat.
And If everything works fine, when you face an opponent creature and win the fight by killing the creature, you should do 2 damages from your creatures combat abilities plus 1 damage (at least) from your "Blood singer" plus 1 damage and 1 faeria from your "Blood obelisk" (protect it well), and if you've summoned one of your "Lord of terror", he'll gain as much attack as the damages done to your opponent, which should be at least 4 here in that example.
-When you play "Hellfire", this can be the jackpot for "Lord of terror" (save it when your "Lord of terror" reach the enemy orb, just before the attack).
-"Bloodstone sprite": this creature is, to me, underrated. It is cheap (4/4 for 4 faeria and only 1 red land), and once on the board, even if it is another creature which is harvesting faeria from an opponent's well the damages will be done (meaning that u can protect it and expose another creature to collect faeria, and if u've got 2 of them, only 1 creature is needed to harvest and the 2 damages are done (4 if u harvest on both wells!).
Like i said above i hate playing against this deck because it often wins without thinking a lot, it's cheap (for example you can remove "Ignus, the first flame" and add another "Blood obelisk" but my advice is to keep "Ignus" in the deck, he is perfect here), and the deck is regular.
Mulligan: avoid "Lord of terror", "ignus, the first flame", "Gift of steel" (except if u've got another creature with combat ability), seek for "Blood singer", "Grim gard", "Groundshaker", "Shedim brute" and "Seifer, blood tyrant" (even if he costs 3 red lands, this is a very good card, above all if your opponent plays a rush deck).
Have fun (and respect your opponent)
Note: removed 1 "Bloodstone sprite" added 1 "Blood obelisk"
