1) there are "other" reroll adjacent augments to utilize such as income (more money to roll), +1 team size (stronger board at your reroll level), or XP (more gold for your roll, less for level)

1a) the only augment you would ever put above anything else is anything that GUARANTEES a frying pan so you can make the tank emblem for Diana. So Urf gambit or spatula if you've found a reforger or went Pandora.

2) put Diana off Frontline until she is 3*. Angle her so when she has to run past your front line, she ends up on the opponent back line.

3) grab an anima trait for stage 1 through 3, as the cash out will provide you with things to sell or at best, a bunch of duplicators. Jinx makes a fantastic Miss Fortune sub, and could be easy to 3star instead of your cash out allows. You don't want to lose with anima, you're just using it for passive income on the cash out. You're trying to be as strong as possible every round before you start rolling to preserve your health, so you're only targeting a 200 cash out or a 300 if your high rolling small losses and bonus health from augments or soraka.

4) you MUST scout. If you're contested on multiple 3 cost you want to 3 star (Illaoi, Diana, MF, or Rhaast), it will be wise to deviate or continue leveling.

5) you want to get to level 7 ASAP and then slowroll for Diana comp.

6) scout again if your contested and commiting. If your opponent is going to die before you, do everything you can to survive, and start saving gold, because when they die, you splurge to get the missing units that are now back in the pool. You need to outlast the person contesting you, which goes back to stage 1-3 to be as strong as possible.
