So I'm pretty hot on trying Ramunap Excavator in a few decks, and the ability to run 1 and grab it with Green Suns' Zenith has me intrigued. I've done a little searching myself but I haven't found much that really excites me.
- Dryad Arbor is a classic pairing, it kind of fights with some vintage mana curves, but it costs you very little to run it.
- Manglehorn's status as an Outcome-hoser with anti-shops applications has me curious
-Leovold, Emissary of Trest is a powerhouse with a tricky mana cost and Legendary status, two things GSZ might be able to help with.
I like that those 3 cards are all things that are worse in multiples, and serve specialized roles in specific matchups. A GSZ build would increase your chances of finding them when you want them, and reduce your chances of having dead Manglehorns stuck in your hand against Mentor.
I don't like that most of these cards are 3 drops, meaning GSZ costs an unwieldy 4.
What cards might you consider running in a list with Green Sun's Zenith?
For each card you suggest, how many do you expect to run? (i.e. is this a specialized tutor target, or a staple that just gets extra redundancy from GSZ?)
If you're thinking about a card that doesn't already see play, why do you think it's close enough to good that GSZ puts it over the edge?
