Love the list! I feel like the main issue is that as of right now, Seasoned Warrenguard can't attack as a 3/2 on turn two which hurts the curve, and unless you draw hop to it, it won't be able to do much at all. Maybe a card like carrot cake or tough cookie if you need that redundancyHunter’s Talent instead of Get lost for your removal because your big bunnies should be large enough to take out any creature, and won't get death touched back, then you can also attack a planes walker easier if thats the issue. Valley Mightcaller might be a good One drop replacement as well!
Mightcaller is a much better one drop imo. Sure it doesn’t get pumped or scry from Questcaller, but a single Hop to It gives it 3 +1/+1 counters, and it has trample.
not me getting Bugs Bunny sleeves and bunny ears to wear to FNM... Oh hey, [Brave the elements] is good, but would you consider [Emerge Unscathed] ? it's single target BUT it has rebound, so you counter that black kill-spell and on your turn can't be blocked by black creatures for example
Emerge Unscathed isn't Pioneer legal but even if it was I'd still prefer Brave as it protects most of the creatures and is fantastic at avoiding blockers.
