mtg burn cards Izzet Counter/Burn Deck - Blue Red - Modern Legal - Custom Built - Magic The Gathering - it loses indestructible until end of turn 3 Mono Blue Burn Spells

4 Koth Of The Hammer Doubles Your Current Red Mana Koth of the Hammer is a red Planeswalker from Scars of Mirrodin

This will make your deck play dramatically better by giving you the best chance to cast a creature that matters every turn of the game

2 Atraxa, Grand Unifier Bring Them All Together Atraxa is a bit more of a wildcard than an exclusive lifelink card, but it just does so much work that it is hard to ignore

Alternatively, you could go the spell route and include cards like Relentless Assault, Final Fortune,Last Chance and Warriors Oath to guarantee yet another round of combat to close out a game but that seems like another deck entirely
