The Leader effect, which allows you to draw a card every turn at 1 cost, is very powerful, but it can only be used when you have 6 or fewer cards in your hand
Once you level it up all the way, though, its a legitimate wincon, allowing you to loop ETB (enters the battlefield) triggers and create a stockpile of Food as you quickly mill your opponent out
If you play it for the Overload cost, it applies this effect to all of your creatures
If one or more tokens would be created under your control, twice that many of those tokens are created instead
Since the card's initial release, other cards with similar but weaker effects have been printed, such as Lotus Petal, which is functionally identical but provides one mana instead of three
