Card of the day: Howl of the horde
Pros: Doubles your finisher and easily triples it. Casting it off Jeleva or Jeskai gal is instant free activation. In standard it turns a painful shrapnel blast or stoke the flames into GG. Seriously, raid is stupid easy to activate and this is the best raid effect so far. Between this and Sarkhan, monored aggro/burn has all the tools its needs to dominate (deck list with this, stoke the flames, sarkhan. Chandra, rabble master, generator servant, prophetic flamespeaker, generator servant, lightning strike and magma jet. Maybe foundry street dude. And whatever else comes out its only 11 different cards and you don’t 4 of walkers.)
Cons: best I can do is that its sorcery speed and not instant.
Rating: staple in any spell slinger EDH IMO, standard RDW staple.
Fun fact: I will make and run this deck until I howl into another howl into a stoke for 20 damage. This is the most Izzet thing I’ve seen since overload.
