Crownwatch Recursion

A deck with many early game units that repeatedly buff themselves to become end game threats.

Safe Return
Crownwatch Paladin
Inspire
Ageless Mentor
Xenan Obelisk

These cards all work together to buff up Crownwatch Cavalry, which once played can be replayed repeatedly using safe return and Praxis Displacer, which doubles as a finisher removing important blockers.

Silverwing Familiar is the primary target of Crownwatch Cavalry, together with Crownwatch Paladin, safe return can refresh the aegis of these two cards and they will keep any buffs applied to them by Crownwatch Cavalry
