It took a while, but when seeing the magecraft ability, the storm-keyword came to my mind. There are some possibility's in building this in other colours, but in the end I did choose white and red.

Lagonna-Band Trailblazer is a great cmc1 creature as it will put a break on most aggro decks and is bolt-proof. With a Eager First-Year and/ or Burning Prophet on the battlefield you should let loose your cantrips, draw cards and try to build up a storm counter to unleash a Ground Rift.
The deck will only have one chance of striking a winning blow, so you should be careful when to attack.
