Get Purphoros out, then keep making those tokens.
Face damage for days.
Based on and inspired by Harook's Purphoros, God of Tokens. Changed to reflect the cards I actually have.
Sideboard Strategy
Tokens: Bring in Anger of the Gods, Arc Lightnings, & Erases, removing the Devouring Lights, Howl of the Hordes, and a Wingmate Roc.
Reanimator: Need to deal with Whip of Erebos, so drop the Howl of the Hordes for Erases. Bring in the Anger of the Gods, dropping 3 Stoke the Flames if it's Sultai so you can sweep away Zombies & Sidisi, Brood Tyrant. Drop the Lightning Strikes and 1 Launch the Fleet instead if it's Abzan reanimator.
Tempo/Aggro: Bring in Nyx-Fleece Ram, Anger of the Gods, Chained to the Rocks, Lightning Strike. Drop slow stuff: Howl of the Horde, Launch the Fleet, Herald of Anafenza. Reduce reliance on mainboard game 1 strategy by dropping 1 Purphoros, God of the Forge, 1 Hordeling Outburst, and 1 Raise the Alarm. Gotta change where they think they're building tempo or swinging wildly against.
Heroic: Weak match-up for us. Don't need Howl of the Horde or Launch the Fleet. Try bringing in the Nyx-Fleece Rams and maybe some Anger of the Gods? Depends on what they've got. If you see Hero of Iroas, maybe bring in Erase. Really tough.
Control: Mulligan aggressively here. You need to curve out really well to land the good stuff, since this is another tough matchup. An early Nyx-Fleece Ram could keep your life high enough to handle late-game Pearl Lake Ancients. Another play-it-by-ear situation.
Burn: Bring in Nyx-Fleece Rams for 2 Devouring Lights. If you see Jeskai Ascendancy, bring in the Erases for the other 2 Devouring Lights, too.
And, since Gods can appear in any of these matchups, find room to bring in Deicide. It's a definite if you see the mirror. Same goes for Jeskai Ascendancy, which is why Erase is there, mostly... but, remember Deicide hits it, too!
