I’ve essentially thrown a ton of cards that are great with the Evolution Sage and Fertilid combo – put in stuff like Merfolk Skydiver as back-up Evolution Sages and a powerful mana sink, and have Incubation to dig for Evolution Sage. I’ve seen how big Evolution Sage can go in War of the Spark Limited, and it’s quite the sight to behold… This is certainly the deck I’m most excited to try myself, though how good it is really depends on how easily people can kill Evolution Sage and Merfolk Skydiver; if all you’re seeing is Red, it might be time to look elsewhere, but if they’re trying to grind with interactionless Mutate stuff, this should go way over the top!
