The spolier for Roselia's pre-evo:
Subomie L.6 – Grass – HP40
Basic
Poke-Power: Baby Evolution
Once during your turn you may play Roselia from your hand on top of Subomie (this counts as evolving Subomie) and remove all damage counters from Subomie.
[.] Errand: Search your deck for a Trainer card, show it to your opponent, and put it in your hand. Shuffle your deck afterward.
Weakness: Fire (+10)
Resistance: none
Retreat: 1
It does have the same attack, unless it means trainer cards that are called "Trainers" (normal trainers, tools, TM's).
It's a riskier play as it has little HP.
Raikizen - if it gets you any trainer card, that it will be another Mawile, that people will use if they don't use Metal energies or will use it after Mawile is rotated out. It may end your turn, but it will set you up for next turn very well.
