How about/ every single spin of the lotto give you a screen like the level up "select a card" screen and let you pick a card of a color (probably of equal rarity)? This way, you avoid auto-recycles, and can assemble playsets faster, without affecting rarities?
Nerf Elite Fencer. Change start skill to "target unit of agi 4 or higher gets AGI = 3. Then, this unit gets AGI = 4 for this turn and ATK +10"
For the great justice of the diverse meta.
