It is far too easy to do an extreme amount of damage with this card. My opponent played Unruly Catapult turn and Ojer. Next turn he cast Titan's Strength on Ojer (making him a 7/5) then did 7 dmg with the catapult, cast End the Festivities for 1 and dealt 7 more dmg to me then to all my creatures (wiping the board on my side). Next they untapped the catapult dealing 7 dmg again. Next they cast a 2 cost draw/discard spell and dealt another 7 dmg to me with the catapult again. Finally my opponent attacked and dealt 7 damage.

Aloow me to sum it up. For 5 mana my opponent dealt 21 damage by casting spells that were less than 2 to cost with a selective creature wipe on top of everything else. Even fiery emancipation isnt that dangerous
