Saati is my main character, 80% of the time spent in the game I played with her, and this deck is my favorite and most frequent by choice (52 lvl 3.7 KDA 60% WR). I think this deck is the most fun to play, if you exclude bugs - the inability to shoot after using the ultimate, from time to time a complete loss of energy, etc.

Cards:
Steady Predictions (5) - take only the maximum level, with this card you will be able to use Wallbang every 16-20 (approximately) hits on enemies with a Ricochet - this is 4 uses of the coin.

Designer Armor (2-5) - often you die - use as many points as possible, you can distribute the remaining points to Bullet Hopper.

Bullet Hopper (2-5) - not enough ammo - use as many points as possible, you can distribute the remaining points to Designer Armor.

Aggressive Tip (1-3) - it all depends on your aim (and reaction if you use a Ricochet near), if you rarely hit a coin, use 1 point, if everything is fine with the hit and you want the coin to fly faster and further, use 3 points. I don't see the point in using more points, because it becomes harder to hit the coin and it's just not worth it.

And last point use on filler - Step Off, Grab and Go, Costly Physics - everyone is good, but I prefer to use Grab and Go because 1 bullet in a close 1-on-1 battle can decide the outcome of the battle.
