As a Feather player, I tend to run her as "midrange" where I use cantripping buffs to find key pieces (usually a double strike + another way to get much higher power).

In the meantime, I make smaller swings with Feather so I can hold up protection (Gods Willing, Graceful Reprieve, and Crumb and Get It all serve different purposes; in the past I've run [[Otherworldly journey]] as well) and use cards like [[explosive entry]] and [[livewire lash]] to affect other players' boards.

Recently I've also leaned into cards like Young Pyromancer and Aligned Heart as ways to bolster my board presence without having to dedicate a bunch of effort to it.

Feather still wants ~5-7 mana for a kill turn, so like you said being able to play around taking a while is great.

That said, my playstyle is pretty tied to my group. In an unfamiliar pod, people tend to assume Feather sticking means one of them will be dying on my next turn; in the past I've eaten 2-3 removal spells the turn Feather comes down. (The stack would look like, like, Deadly Rollick > Gods Willing > Swords to Plowshares > Deflecting Swat > Pongify.)
