While Legacy was a popular format because of the inclusion of powerful and nostalgic cards from the HeartGold & SoulSilver era, its time is seemingly over
Its completely normal for a single turn to be composed of ten different actions that build on each other just to get a single pokemon evolution, for example, which sounds annoying but is satisfying in practice
Nantuko Shrine also generates a bunch of tokens, but it wont do much in a singleton format
When the tokens show up, they trigger any ETB effects on the creature you copied
The same kind of thing can be explored with artifacts like Baton of Courage, Embercleave, and Scale of Chiss-Goria
Legacy Burn can run fetches for deck thinning, but those dont stay on the board long
