Personally, I prefer to use Imotekh the Stormlord as my Commander, though, letting you create token creatures as you use recursion and power up a creature during combat
A clue token is a token artifact that allows you to pay two generic mana, tap it, and sacrifice it to draw a card
These will transform after you fulfill some kind of condition on the card, usually either an activated ability (i.e., paying to exile Terra, Magical Adept) or triggered ability (i.e., having six permanents in the yard for Exdeath, Void Warlock at end of turn)
Faline can easily bump up her Lore score to a three if the parameters of her ability, Precocious Friend, are met
There's a promo card variant with the Magic logo stamp, for instance, which has understandably remained cheap
You get points for attending, bringing friends, teaching others how to play Lorcana, and more
