This Tavern Brawl sees players doing battle with custom decks in the Wild format. Every third spell cast each turn costs 0 mana, just like the effect of Kael'thas Sunstrider. Try to cast 3 spells if you can. The third spell can be a high cost card for greater value. You can easily pull this off my using your low cost spells like Font of Power, Magic Trick, Tome of Intellect, etc. If you have Learn Draconic, cast it as much as possible to benefit from your spells. You will get your dragon in no time.

One of the spells I want to point out is Evocation. I don't have it here but if you have it on your collection, you can add it. It will give you a pool of spells to choose from. It will disappeared after your turn so casts your desired spells as much as you like. This a good finisher too!
