I never even thought adding the Agenda w/ the Wild Research. Wow, this could be very, very strong.
You've got some great elements in here: The Accumulated Knowledge has natural synergy with the Research, as does the Nether Spirit (which seem work well with everything).
I would consider including some more power-instants into the deck to milk the full potential out of the Research. Just like the old silver-bullet decks, you should only need 1 of each to work
Some to consider:
Tsabo's Decree
Dominate
Opportunity (I still think this card is underrated)
Backlash (Another one I feel is underrated)
Evacuation
Undermine (maybe just one to get around a Worship)
The key here should be trying to go after pure card advantage spells.
Anyone know of any instant mass destruction ala Fault Line?
Of course what to cut is always the difficult part:
Maybe the Briberies, they are great cards but I think they might be limited in scope being sorceries when its the instants you can be abusing. They are nice though
1-2 Urza's Rage maybe, another tough call but 4 might be overkill.
1 Prophetic Bolt, it is very hard for me to say cut this card b/c I absolutely love it, but you've got great search already.
I'm torn on Teferi's Response. Maybe run 1. Normally I'd suggest definitely putting it in the sideboard but now Vindicates are targeting lands too that you have to worry about.
Awesome deck, its inspiring me to build something similar (and I will give you full credit for it
)
