any suggestions for jeska/kydele planeswalkers?
Mmmmh, I imagine you have everything you need when it comes to counter support, with both blue and green. Though on that end I will affirm support on Pir and Toothy if you aren't running them and have the budget.
Pir buffs the starting loyalty AND activation loyalty of your planeswalkers, and Toothy rewards and enables the same card draw Kydele cares about.
As far as less obvious recommendations, take a look at some goading! Goaded creatures can't attack planeswalkers, so they do a good job at protecting them from their most vulnerable point in commander, even when you're down to 1v1 when Goad effects often lose a lot of value.
And now, something for planeswalkers in specific in the deck:
All planeswalkers are legendary permanents with spell-like activated abilities. The Dynamo being a good blocker on rate that can copy your planeswalker activations for a single mana is pretty great! Sadly it can't copy Jeska's activation to turn it from 3 times damage to a whopping 9 times damage, but that's fine. The other two CAN do that, giving you a bit higher a floor, but they're more clunky in other ways.
Return the Favor is pretty versatile in what it can do, from copying a powerful spell instead to moving away pinpoint removal, but it's a one shot effect. Rings of Brighthearth does the one thing repeatedly, but it quickly becomes clunky in mana... If only you had a commander that could generate a bunch of colorless mana you need an outlet for.
Of course, the dream is to copy a planeswalker ultimate, but in reality, any minus and a fair few plusses are good enough you'll be happy to double up on them. Sadly you aren't copying the loyalty cost to put more loyalty on your planeswalkers, but still pretty good!
