Anyway, this is my Chisei deck - tbh it's pretty cookie cutter EDHrec stuff, since there's not a ton of wiggle room on synergies. Sagas provide a decent number of strong targets for Chisei's ability, in addition to the more random one-offs like Quicksilver Fountain and Thing in the Ice // Awoken Horror.
Between those and a handful of other token removers, though, is only about 20 cards, leaving 40 slots or so for whatever. Mostly this is filled in with cards that WANT counters or add counters, which *kind of* has synergy with Chisei insomuch as it gives him (her?
it?) a place to steal counters if a better option isn't present. Truthfully I think the "better" version of the deck probably plays a bunch of classic mono-u control stuff instead, since the synergy is a bit tenuous, but I've built too many mono-u control decks in my life so we're going full-on counters jank, with a few of the best control spells added just for a semblance of seriousness.
Ok here 'tis.
