Mono red dragon shenanigans. The goal is to cast as many spells as possible from your opponents' decks. Etali, Primal Storm, Stolen Strategy, and Grenzo, Havoc Raiser all work great. Try to give your creatures Double Strike with Berserkers' Onslaught or Rage Reflection to multiply the Grenzo triggers. Helm of the Host can also be attached on Grenzo, Havoc Raiser to double his triggers. Try to avoid casting spells in your first main phase so you can save mana for Grenzo, Havoc Raiser triggers in the second main.
Use the dragons to aggressively attack players and Planeswalkers. Urabrask the Hidden is very powerful and his tap ability will win you games. Get Loxodon Warhammer out as soon as possible to gain as much life as you can. Having Dragon Breath in your Graveyard works really well with some the dragon cards like Dragon Mage, Steel Hellkite, Scourge of the Throne, and Hellkite Tyrant.
Fork, Reiterate, and Reverberate are extremely versatile and can win games. They also can act as a surprisingly strong counterspell package against blue. Word of Seizing is usually unexpected and can win games by stealing a Planeswalker who is about to ultimate. War Cadence can be activated during another players combat to make their attackers Unblockable. Banefire is uncounterable and can take out a control player unexpectedly.
