eco base ideas:
Cardinal: yh, ill leave this one unsolved, its a pain for sure. unless mindflayer +regrade dims actually works
Higgs: wings + excessive pc and any kind of wincon; dont have to worry about cc or pc at least and only ug bypasses wings iirc
Matrix: sosac/dials kinda a must vs a rush with all dmg types, but obv sosac not an option and dials nerfed too hard (silence is a pain for that strat as well, but its not that hard to slpash sanct/dream catcher)
can try to mimic entronymph spam with nt but that seems too slow
oty also has potential, as it deals with recluses right away and limits byt use, still gotta deal with lobo, fractal and immortals though; a rainbow stall built around oty or scarab(easier to bring out but needs some help to get going) with some pc and a lot of healing seems promising
Sesha: rt/unsummon should work well here, but need lots of healing to survive the initial burst and remaining dmg. the new counter to catatitat should work well if you replace the pc with stuff that deals with fenghuang and entro cards
Swamp: you need to be mostly unaffected by devs and 8 dmg reduction, as well as a way to deal with despair. deja hope with sanct and midas touch perhaps? with reinforce light dragons to not deckout? and yes thats basically a deck filled to the brim with uncommons. may also go with immo photon as early game way to deal with devs and power luci, which would allow you to then use deflag as pc for despair when needed.
