Instant and sorcery spells you control have Buyback {x}{u}{r}, where X is equal to the spell's converted mana cost plus 2. You may only Buyback each spell this way once per turn.
"Test 1: These spells have been proven to be quite difficult. They are potent but have limited use. Unfortunately, my first attempts of fixing this has been fruitless, but I will succeed."
