We have two potential ramp cards available to us Grow from the Ashes and somethings that’s currently called Detour on MythicSpoiler (it’s known as “This garden is 90% full of snakes!” on Scryfall), which is a strictly better Explosive Vegetation as it can find Gates as well.
How about this play pattern: Electromancer into Detour into Primal Amulet and… something. Or better yet: Elfhame Druid into Detour into Primal Amulet and Grow from the Ashes 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.
Most of the time this deck will just die against anything aggressive, though.
