When Neva enters, return target creature or enchantment card from your graveyard to your hand.
Whenever an enchantment you control is put into a graveyard from the battlefield, put a +1/+1 counter on Neva, then scry 1.
Neva is an Orzhov enchantments-matter midrange/aristocrats deck that grinds value by recurring threats and sacrificing or cycling enchantments to grow Neva and dig with scry. You deploy cheap enchantments and creatures, leverage Neva's ETB recursion every time she returns, and turn dying enchantments into card selection and an evasive Voltron threat.
Built-in card advantage: every recast of Neva returns a creature or enchantment from the graveyard.
Grindy and resilient against board wipes thanks to recursion and graveyard value.
Menace plus snowballing +1/+1 counters makes her a real commander-damage threat.
Scry 1 triggers smooth your draws and stabilize land/spell ratios.
Slow to close games without a payoff; pure value can stall.
Counter growth requires enchantments actually dying, which needs sacrifice/destruction enablers.
Vulnerable to graveyard hate that shuts off her recursion engine.
Two-color, so no access to fast green ramp or blue interaction.
