Core rule · Rules Tome 2.0.8 § 503
Draw phase
Discard any number of cards, then draw one at a time up to hand size.
How it works
Full rule
Each player may discard any cards from hand, then draws until their hand equals their current hand size. A player already above hand size neither discards down nor draws.
At the table
Example
With three cards and hand size five, discard one card and then draw three.
Watch for this
Common mistake
Hand size is not a maximum hand limit.
