Sample hand, Draw and Mulligan simulation

To see what your hand would be with current deck use sample hand tab. You will see the buttons

• new hand shuffles the library and deals you 7 random cards
• mulligan shuffles the library and deals you N-1 random cards where N is current hand size
• draw adds 1 random card to your current hand

Deck editing commands such as adding / removing / reordering cards still work in sample hand tab. Combining card removal with middle mouse click with draw button you can simulate your hand content within the match.

window header buttons are mostly related to editing deck / collection
