Can you evolve a Pokemon in the TCG on the first turn?

Question

When a Poke-Power/body activates, such as the baby Pokemon's "Baby Evolution" Poke Power.

Answer 1

>Pokémon cannot be evolved on the first turn of the game or on the first turn they come into play. They also cannot be evolved if on the same turn they were previously evolved or devolved. -Bulbepedia

So no, it can't evolve on the fist turn. You'll have to wait for the next turn.
Hope This Helped :D
