Casual multiplayer burn deck. No need to attack; just sit back and watch them all burn. Midrange mana curve (Can't trim the 3-drop spot), mono red. Intended to be Modern, but Tempt with Vengeance is pretty tempting.
Burners: Guttersnipe & Purphoros, God of the Forge
I feel like Guttersnipe is underused in this deck and am considering swapping out for Krenko and his goblins.
Trigger both burners:
Molten Birth
: Recurring
Tempt with Vengeance(This is a casual deck)
Trigger Purphoros and generate tokens for defense:
Elemental Mastery: Recurring Purphoros trigger
Mogg War Marshal: Triggers Purphoros 3x
Pentavus: Recurring Purphoros trigger
Thopter Assembly: Triggers Purphoros 5x, then bounces
Young Pyromancer: Amplifies Guttersnipe, triggers Purphoros...but is a 2nd-order support card
Trigger Guttersnipe:
Reroute
: Trigger Guttersnipe and splash in a bit of counter
Get burners onto the field:
Chandra, Pyromaster
: Could use a better Planeswalker for this deck
Crystal Ball: Tap to Scry 2 every turn. Don't plan on attacking anyway.
Infiltration Lens
: Opponents choose to let me ping for damage or draw two...kinda doesn't fit this deck's goal, though.
Magma Jet: Here more for the Scry than the burn. Maybe swap for a spell that creates tokens?
Mind's Eye
Some defense or attack deterrents (most also trigger Purphoros):
Dragon Egg: Deterrent and trigger Purphoros 2x
Kargan Dragonlord
: Mana dump & late-game option
Kazuul, Tyrant of the Cliffs: Deterrent and recurring Purphoros trigger
Lightning Greaves: Protect a burner
Magus of the Moon: Slow opponents down
Mindsparker
: Punish Control decks
Slumbering Dragon: Deterrent
Late-Game:
Akroma, Angel of Fury: Alternate late-game win condition. Morph is Instant-speed, but doesn't trigger Purphoros a 2nd time.
Hellion Eruption
: Trigger Purphoros (if not a creature) and buff up for an attack. Will trigger (and sac) Guttersnipe. Somewhat situational, but can end multiplayer games quickly in this deck.
Optional Goblin variant. Could use Guttersnipe more, or replace with ...Krenko, Mob Boss:
Dragon Fodder and/or Krenko's Command
Krenko, Mob Boss
Empty the Warrens
Goblin Rally
