Other multicolored creatures you control get +1/+0.
Whenever another multicolored creature you control dies, return it to its owner's hand at the beginning of the next end step.
Rienne, Angel of Rebirth is a Naya value engine that flings out aggressive multicolored creatures, recurring them from death to your hand for nonstop pressure. You ramp into a board of gold creatures, attack with the team buffed by Rienne's anthem, and grind out opponents through superior card advantage and resilience. Win by going wide/tall with multicolored beaters or by abusing repeatable ETB effects from recursive bodies.
Built-in recursion makes your multicolored creatures extremely hard to kill via removal or chump-blocking trades
Free +1/+0 anthem turns a gold-creature board into a fast clock
Color identity gives access to elite Naya ramp, removal, and tutors
Synergizes with ETB and death triggers since creatures keep coming back to hand
Recursion only works while Rienne is on the battlefield, so she's a removal magnet
Bounce-to-hand still costs you mana to recast, which can be tempo-negative
Heavily reliant on multicolored creatures, narrowing deckbuilding
Vulnerable to exile-based removal and board wipes that exile
No inherent ramp or card draw from the command zone beyond recursion
Tutors any creature, letting you find Rienne or a key multicolored threat on demand.
Lean harder into mana acceleration (Birds of Paradise, Cultivate, Sakura-Tribe Elder) so you can recast bounced creatures without losing tempo. Add powerful multicolored ETB engines and free sacrifice outlets to convert the recursion into a value loop, plus protection like Heroic Intervention and Teferi's Protection to shield Rienne. Top-end tutors and a couple of clean combos (e.g., creatures with abusable ETBs and reanimation) push the deck from midrange grind into a faster, more reliable kill.
