Rescuer Chwinga

Flash on a two-mana body is the enabler here, but the return clause is what gives the Chwinga its job: an instant-speed way to save one of your own permanents from targeted removal, a board wipe you see coming, or an exile effect on the stack. Hold it up, let an opponent commit to killing your key creature or blowing up your enchantment, then flash this in and bounce the threatened permanent to safety, replacing it with a 2/2 that also happens to reset any enters-the-battlefield trigger the returned permanent carries. The bounce is optional and reads "another permanent," so the ability never fizzles: if nothing needs rescuing, it enters as a plain flash blocker. That flexibility is the whole appeal. This is a defensive tool built around timing rather than raw stats, rewarding a player who leaves two mana open and waits for the moment the return actually matters. The Chwinga themselves are a recurring flavor thread across recent sets, small elemental spirits whose mechanics tend to key off protection and reward, and Natural Shelter fits that identity cleanly: an ability word that dresses up a self-bounce as an act of sanctuary rather than value grinding.
