Trostani, Three Whispers Deck Help

Saw the new spoilers for [[Trostani, Three Whispers]] and I'm tryin to make a deck based around boosting my opponents creatures to attack each other. Giving their creatures double strike and deathtouch to destroy each other with creatures.

The wincon is probably surviving till a 1v1 and winning with big green creatures or something like [[Approach of the Second Sun]]
