Touhou LostWord Divergent Spirits C3 Marisa farm (?), possible.

Ain't posting proofs on discord channel cause I'm just too lazy taking screens, specially when I don't go past 40 runs per farming session.
I have tested different ways with different cards, 3t should be possible with double LW Shinki + Yuyuko during second turn and Koishi using her AOE spell card to erase the stragglers, problem is you need at least her 3rd skill to be available on last turn, second with all skills on cooldown Marisa will survive, it will prolong the drill and possibly cause a wipe.
4t strat should be doable at 15sp too, but I'm not taking risks

discard this, it ain't a farm, fucking Marisa is NOW surviving t1 onslaught, 60 tries ago she fucking didn't.
