Glasskite looks like the best control finisher of these three. Sphinx feels very underwhelming and Ephemeron requires expending tons of extra resources to keep it from dying. Glasskite is difficult to remove, but not frustratingly so, and only requires a one time cost to play.Looking for a 6mv control finisher at a low power level here.
I thought about the Swarm too, but I don't like that it's protection won't generate card advantage in any way. Similar to Cerulean Sphinx. And the mill clause seems to add words that will rarely matter.
I'll go with the Glasskite. It's simple, will probably do a good job and I am always happy to add a Kamigawa card with their unique flavor.
Thanks guys <3
My favorite part about Awakening Zone is how much agency it gives to its controller. The Eldrazi Spawn can chump block, ramp into slightly expensive spells several times, or into one huge Ghitu Fire. The Spawn can be sandbagged for Overrun, equipped, and even sacrifice to pay the equip costs in a pinch. The addition of the resource “Eldrazi Spawn” is, in my opinion, what made Rise of Eldrazi a good limited format. It is a resource naturally and elegantly weaved into the game, unlike Energy, which feels more artificial. The game framework itself provides multiple things to do with the Spawn, and the combinations in which the mana can be spent adds a great deal of freedom to gameplay in the format.
I can relate
I like both, but I use Jade Mage for the mana sink. In slower, card-advantage constrainted environments, mana sinks are really useful to give a player a conversion path of mana -> CA. Passing with 8 mana up and nothing to do with it feels quite bad. Jade Mage is at a decent point in the conversion in that it's not something you often do when you have other cards to play (so it's not repetitive), but the rate is good enough that it can break a board stall over time. Also secret synergy with counterspells.
Don't get me wrong, Nest Invader is great too. Eldrazi Drones are an elegant agency mechanism. Quoting myself from https://desolatelighthouse.wordpress.com/2020/12/14/awakening-zone-one-card-a-day/:
