Thought I'd consult the brains trust and see where it leads.
This weekend I'll be taking this to a constructed standard event. It's a greedy deck aimed at hitting 7cmc quick, and spamming Agent repeatedly.
It's not clever or even competitive, but I find it fun to play.
Just a quick mock-up. I need to spend a bit more time with card choices obviously. Panharmonicon seems like a nice alternative to Yarok, so I'll probably make that swap. Blade of Selves could easily be in multiples, but given Thassa blinks creatures, paying the equip cost turn after turn might stagnate my attacking with Blade.
Arboreal Grazer is such utility in decks like this, I absolutely want to see it turn 1/2. Her big butt and reach helps to stifle those early attacks that will now be sent in your opponents direction. 28 lands feels like the right amount in Field of the deadArboreal Grazer decklists. I realize you have turn 2 Baleful Strix which is also awesome, it only trades and doesn't give you free blocks early.
With regards to Reclamation Sage I tend to only run one from days past. However, you know your meta better than we do and perhaps you need multiples? I mean it isn't really toolbox deck so I wouldn't fault anyone for running more than one copy
