Sleeve Draw...

[Mimilu]

I wait until I have a card I want on spread, balance or spear and then pop it. I usually have good luck with it such as getting a group spread when I do that. So pretty much used when it's off cool down.

This is what I do.
Draw and Spread a Balance, Arrow, or Spear then use Sleeve Draw to fill in the rest. If the card in the Drawn slot is a Ewer or Spire and my Royal Road isn't AoE, I'll Royal Road them for an AoE.
