Spellshaper Adept

When Spellshaper Adept enters the battlefield, exile an instant or sorcery card with converted mana cost 3 or less from your hand. As long as you control Spellshaper Adept, you may cast that card from exile, and it gains Ambitious. (You may pay {1} and discard acard that shares a color with this card instead of paying this card's mana cost)
A spellcaster's true purpose is to achieve anything, at any cost.
