Pricing is on the steeper side
Noone expects that, unless theyve seen it happen
The discard is sorcery, costs 3 mana to get online and only does one discard per turn of their choosing while also forcing you to discard
If you use Zaras ability and then flicker the creature with an effect that specifies the flickered creature comes back under your control, you get to keep the creature forever since it counts as a new instance of the permanent

For removal, run creatures aswell, id get Foundation Breaker, Druid of Purification, Bane of Progress, Haywire Mite, Reclamation Sage, Voracious Hydra, Acidic Slime, Duplicant, Kogla, the Titan Ape, Meteor Golem, Terastodon, Woodfall Primus, Ulvenwald Tracker For draw, run creatures aswell (your starting to see a synergie?) Beast Whisperer, Voice of Many, Toski, Bearer of Secrets, Augur of Autumn for ramp you have the mana dorks, Sakura-Tribe Elder, Fertilid, Wood Elves Elvish Pioneer, Primeval Herald, Skyshroud Ranger, Selvala, Heart of the Wilds For bombs, id run creatures that already have trample, Defiler of Vigor, Neverwinter Hydra, Ochre Jelly, Kalonian Hydra, Aberrant, Craterhoof Behemoth and a tutor: Fierce Empath some other cards i would consider Champion of Lambholt (makes your creatures unblockable, Saryth, the Viper's Fang hexproof untapped, deathtouch when attacking (insanely powerfull with big trample creature)

Maybe give KLL a shot in your next reanimator build, I really think it can have a big impact on games
