Legion's Wrath 

Ever wanted Blasphemous Act to hit face?

Commander - Tajic, Blade of the Legion

Decklist

I love burn, and I love elaborate combos that kill people in interesting ways. This deck has a single-minded focus on both of those. Play a Wrathful creature (an unofficial term for creatures that deal damage when they take damage), cast a big red damage spell, and destroy your opponents with double digits of damage.

Tajic, Blade of the Legion was the best of surprisingly few commander options for this strategy. Ojer Axonil, Deepest Might lends itself to a very different kind of burn deck, buffing up small pingers. Iroas, God of Victory was considered, but it's not a creature half the time. And that's it - Tajic and Iroas are the only two Boros commanders that innately have Indestructible. This is important for the deck's backup plan.

There are only so many good Wrathful creatures, and only three of them survive getting hit by a Shivan Meteor. Having one in the command zone would help a lot with consistency. And it just so happens we can build one - Blazing Sunsteel turns Tajic into a Wrathful creature, and Boros has plenty of equipment tutors to fetch it or an Indestructible-granting equipment to help our more fragile Wrathful creatures survive the meteors.

I included a lot of damage doublers in this deck, and that's because they often actually result in quadrupled damage: If you cast Shivan Meteor while controlling Dictate of the Twin Gods and a Wrathful creature, your creature will take the doubled 26 damage. It will then redouble that for a game-ending 52 damage to an opponent of your choice.
