Newbie Question

[La1cajun]

Thanks for the answers. So when i go to charity move...do i give people as many as i want..like if I have 8 cards, can i give one person all them..or is each person only get 1...like if its just me and my son playing, would I give him 3 cards if he was lower than me or just one and discard rest..or is it my choice.
Second, so in combat, i can have an elf played on the table, and change it to a halfling if i want right in the middle of battle if it will benefit me in some way or form? Ty so much for your response and helping out. I think its a fun game..just want to make sure i have the rules right.
