Seemed very solid all around. The real wiggle room is the Maindeck 4th Revoker, 4th Crop rotation, 2nd Candelabra, and 2nd Ponder. If your meta is RuG infused, I suggest a 4th Show & tell, Storm, a 4th revoker, reanimator a 4th Crop Rotate, Holistically even in spread, a 2nd Candelabra.

Khalni Garden was amazing in all my matches. Blocked a bob to save my life and win the game. Used it to repeal/draw for 1 blue. Blocked 2 dmg versus DnT. Had to be Bolt'd for a Liliana to kill a Titan, which resulted in me living at 3 life at the end of the game. Went fog-crazy versus Mud against Wurmcoils and Lodestones via Vesuvas to stall me into a win.
