The finnicky nature of the Gallery definitely detracts from the overall experience, since I have no idea if my creations will be saved until after I exit away from them (in which case theyre gone for good if they didnt save)
You and your opponent start off with a certain amount of life points, i.e
Legendary Creature - Advisor Fox Phelia, Exuberant Shepherd Flash Whenever Phelia attacks, exile up to one other target nonland permanent
At just 2 mana, it asks you to already have a creature with power 4 or greater, but in return it delivers a flying copy that can immediately pressure life totals or planeswalkers
Your child doesnt have to learn about every card, but having an idea of what their more appealing cards are worth will help them make balanced decisions when trading
Then buy/sell a little to see what is there
