Calamity RDW (Modern)

Still a work in progress, but tons of fun! Very consistent and very fast! Tons of hasty one drops (mostly goblins), things that generate hasty one drops and burn to trigger Cavalcade of Calamity damage and Goblin Grenade to seal the deal.

Each calamity trigger or burn damage sets off Chandra's Spitfire triggers, so that can get huge in a hurry! (If you play it on curve on turn 3, attack on turn 4 and have 3 other 1 drops attacking as well, Spitfire is 13/3 flyer and you get 4 Calamity triggers, plus the 3 for the 1 drops, so a total of 20!

Legion loyalist is a powerhouse here, making stuff unblockable by tokens and giving your army first strike.

When I mocked up the deck, I had Grim Lavamancer in instead of the Goblin Rabblemaster (Didn't have GL on MTGO) but I've liked Rabblemaster when I've hit it in playtesting, so I'm posting it as-is for now. If basically 6 of that type of card are too many (it has 4 Legion Warboss) I might go back to the Lavamancers or go more burn. If you did go down to a 1-drop here, you can cut a land or two from the deck. CMC here is artificially high since you'd never hard cast Rift Bolt.

Monastery Swiftspear is one of my favorite cards, but prowess triggers often make her 2 power, so she doesn't trigger Calamity when attacking, so I might drop her for a hasty goblin 1-drop to have the same guaranteed 2 damage per-swing, and give me more goblins to sacrifice to Goblin Grenade. (that hasn't been a problem yet as there are 16 main deck, plus a lot of goblin tokens being generated.)

I threw in Rift Bolt, because I had them and they rock, but Skewer the Critics might be a better choice here for same-turn activity vs. a suspended Rift Bolt.

20 is a lot of land for this deck. I'll tweak it a bit and find the sweet spot. I tried a Ramunap Ruins, but there are so many red one drops, it could cause you early game inconsistency.

Sideboard: 2 Damping Sphere for Tron, 3 Tormod's Crypt for graveyard shenanigans, 2 Goblin Chainwhirler for tokens/Humans, 3 Dragon's Claw (seeing a lot of Burn in the meta) 3 Smash to Smithereens (for Chalice of the void, etc.) and a couple of Tibalts to stop life gain or have another way to make tokens if they have a lot of sweepers.
