Here’s a deck by Todd Anderson, which does it’s best to kill the opponent with [scryfall]Fight with Fire[/scryfall] copied with [scryfall]Primal Wellspring[/scryfall]. So, what if we go deeper and add some green ramp.

We have two potential ramp cards available to us [scryfall]Grow from the Ashes[/scryfall] and somethings that’s currently called [scryfall]Detour[/scryfall] on MythicSpoiler (it’s known as “This garden is 90% full of snakes!” on Scryfall), which is a strictly better [scryfall]Explosive Vegetation[/scryfall] as it can find Gates as well.

How about this play pattern: [scryfall]Electromancer[/scryfall] into [scryfall]Detour[/scryfall] into [scryfall]Primal Amulet[/scryfall] and… something. Or better yet: [scryfall]Elfhame Druid[/scryfall] into [scryfall]Detour[/scryfall] into [scryfall]Primal Amulet[/scryfall] and [scryfall]Grow from the Ashes[/scryfall] kicked. I have a slight headache right now, so I’m not even sure how much mana you’d have available on turn five.

We do have a bit of a problem here in that neither Gruul or Simic is in the set, so it’s possible that this will be a more functional deck after the next set.
