The Alacrian Quickbeasts (Selesnya) Color Combo: Green/White Strategy: Vehicles and Mounts Midrange Key Cards: Caradora, Heart of Alacria / Earthrumbler / Guardian Sunmare Another Aetherdrift archetype focusing on Mounts and Vehicles, The Alacrian Quickbeasts want to load your board up with both and stack them with +1/+1 counters
Tinker Bell can even deal some additional damage whenever she challenges a character and successfully banishes them
Punishing your opponents for searching their library is also some tremendous upside in Commander, where tutors and fetch lands are ubiquitous
Banning it was perceived to kill a very cool and different archetype, soft-banning a lot of unusual cards
Could also be the mythic uncommon of the set (though these are harder to predict)
They're a harder plastic shell, and if the cards are in clear card sleeves before going in the top loader, it's usually very well-protected and hard to dislodge on accident
