Most notably, that comes into play as agreeing with the opponent on an alternative action that feels fair, or inviting an outside-the-game person to perform the action. As far as Falling Star goes, the entire text box from whats printed in Legends has been rewritten for clarity, and because of that overhaul theres only two added Oracle rulings
Whenever a creature with a bounty counter on it dies, each of its controller's opponents draws a card and gains 2 life
So if you have a 4 mana commander, you should have 32 lands, or if you have a 10 mana commander, 38 lands
Technically, this wasn't the first card to grant you a repeatable Loot effect
Gaining life, creating creature tokens, preventing damage, placing +1/+1 counters on creatures for extra buffs, and removing artifacts and enchantments from the battlefield are some of the other functionality that this color pair has over others
