A lot of people are talking about level 68 spells but no one is talking about pets. here's my ideas:
Fire: Draconian Warrior: Give one card: Flame Draconian: 8 pips 300 and 400 to all enemies and -25% Accuracy to all enemies (A fire wirwind appear and the draconian shoots fire and charging forward. He fly to the enemy and slash with a flame sword). Have Spritely chance and may cast Fuel
Myth: Golden Minotaur: Give one card: Golden minotaur: 8 pips 50, 100 and 700 damage to one enemy and remove all negative charm on all players and allies. ( A Greek temple appear, the Minotaur wearing golden war armor jump out of it and slash in mid-air (first attack) he then smash against his opponent with his flaming ice breating axe like-the-pet. Then, he do a backflip and slash like the normal minotaur spell but it makes a tornado and strike against opponent. He then back out and make a earthquake to remove the negative wards. The animation is shorter than you might have expected. Have spritely chance and may cast myth blade.
