Ill-Tempered Reckoning (Pioneer)

Unfortunately this is far superior to the original "Brash Bash" and I do wish I could still have Brash Taunter, the deck now has an easy to achieve infinite combo and it just doesn't work with Brash.

Goal is to have any of our several damage redirectors on board, cast Take Up the Shield / Angelfire Ignition, and damage our own creature with any damage spell / through combat. You then target your own creature over and over for redirecting the damage and since it has Lifelink this should create an infinite loop of damage and healing that won't end in a draw, because you can throw the damage at your opponent to end the loop.

Truefire Captain can also do this with the help of Gideon's Sacrifice, because Truefire lets us target any player including ourselves.

Marauding Raptor helps us get out faster and can fulfill our damage requirement.

Alternatively you can just win by redirecting a butt load of damage to the opponent with Purphoros's Intervention, that is also why we have Stormwild Capridor in the sideboard, because it will let us be high and big in the sky to close out the game with just damage. Stormwild Capridor is also just a really fun FU to any wannabe burn decks lurking about.
