Cards like Hardened Scales shine with The Swarmlord, as well as cards that place counters on your creatures passively, like Arwen, Weaver of Hope and Renata, Called to the Hunt
Dragons of Tarkir was the dragon set, but unlike Fate Reforged, it had zero dragons at common (though it did have an as-fan over 1 thanks to the preponderance of uncommon dragons)
Adventures in the Forgotten Realms, Strixhaven: School of Mages, and Theros Beyond Death all have good haste cards
Terra's abilities also synergize well with the Esper cards, so it's clear Magic 's designers are encouraging this build
The nice thing with Maze of Ith is that you can use it to untap your own creatures, like those with an attack trigger, so you can get whatever activation you want and keep your creature out of harms way
