Elminster

Legendary Planeswalker — Elminster

Whenever you scry, the next instant or sorcery spell you cast this turn costs less to cast, where X is the number of cards looked at while scrying this way. [+2]: Draw a card, then scry 2. [−3]: Exile the top card of your library. Create a number of 1/1 blue Faerie Dragon creature tokens with flying equal to that card's mana value. Elminster can be your commander.
