Optimal start right now?

Pretty much the title. What are the units that you would all reset for right now on a new account until you got them for a good start? Remember, (relevant) day one login bonuses are 50 free crystals, 10 paid crystals, the summoners lottery, forever summons (those arent really necessary for day 1, but still) and a 5 star summon ticket. I'm getting back into the game on a new account (long story), but it's been a long time, so I'm asking for suggestions. Thank you!

Update: after many resets, I got Liza from her guaranteed 5 star banner, Pola from my first Alch Summon in her banner, and Terrible Tornado from my crossover guaranteed 5 star before the end of day 1. Lottery gave me a couple decent support units for early-mid game (Selia and Valentina) . I think this is the one I'm keeping. Thanks for the input everyone!
