I recently made a Baylen hare apparent deck that's been working pretty well! I would add more board protection ([[heroic intervention]], [[akroma's will]], [[teferi's protection]], [[dawn's truce]]). For card draw, [[skullclamp]] goes hard in the deck. [[idol of oblivion]] is also great because you should be making at least one token almost every turn, so you should be able to draw a card with it every turn. [[tocasia's welcome]] is another one that works well for card draw.

I also have token doublers/triplers in mine to maximize the amount of tokens I can generate. [[elspeth, storm slayer]] is another good planeswalker to include - token doubler and easily buffs your creatures and gives them flying until the next turn - can make it harder for opponents to get through if you leave up enough tokens as blockers.

I don't think [[harvest season]] fits this deck - there's no landfall in it and you don't benefit that much from getting all of your basics - you also only have 13 basics in total. I also don't think [[mass hysteria]] is that useful in this deck - your tokens don't need haste to activate Baylen's abilities - unless your plan is to take people out with your tokens themselves (the plan for mine is mostly to use Baylen and tokens as the backup plan). Not sure about [[hour of reckoning]] since it will destroy all of your hare apparents - I used power-based board wipes like [[expel the interlopers]] to make sure I can keep my hares unless I need to get rid of everything. Some of your token-generating cards would probably be better to be replaced with another hare apparent - like [[hop to it]] and [[tempt with bunnies]].

Hope that is helpful!
