1) is better on account that you can't do 2). You can only evolve a card by adding a first stage card onto a 1st/2nd/3rd stage card.

If you try the second way, you'll get an error message saying you no suitable cards to evolve - I'm in this position with 2 x 2nd stage Eject cards. I learnt the hard way so you don't have to!!
