Adapting modern Obosh aggro to historic.
Notable losses when adapting to historic include Ragavan, Nimble Pilferer, Fury, Fetchlands, and Blood Moon. This is an attempt to keep the rest of the shell intact and replace those cards to gage viability in historic. Replacing these cards is done as follows:
Ragavan, Nimble Pilferer --> Bomat Courier;
Fury --> Glorybringer
Fetchlands --> Ramunap Ruins & Field of Ruin (Primarily for additional reach or putting lands in the graveyard to enable Delirium)
Blood Moon --> No great direct replacement, replaced with Skewer the Critics
This version leans on Bomat Courier and Dragon's Rage Channeler for early aggression and card selection. Turn three we lean on Chandra, Dressed to Kill to trigger spectacle cards in Light Up the Stage or Skewer the Critics, ramp us, or gain card advantage. Seasoned Pyromancer provides additional card advantage when running out of steam.
The remaining cards such as burn spells, or if you can manage to bring out Obosh, the Preypiercer, are for finding extra ways to get in damage and close the game.
The sideboard is mostly targeted towards popular decks in historic. Rampaging Ferocidon is for Heliod Combo and G/B food decks. Relic of Progenitus is for U/R Phoenix decks or reanimator lists. Roiling Vortex comes in for control matchups. Sarkhan the Masterless is for matchups where the opponents removal is light and the match may go longer.
