Poison seeds are probably the most important thing to mull for as it is your best answer to big priest.
A reno deck looking to use the combo of Aviana + Kun the Forgotten King + Innervate in combonation with Elise the Enlightened to get mutliple copies of Ixlid, Fungal Lord and Malygos for a lot of damage. Otherwise the strat is to control the board and use Reno Jackson with Zola the Gorgon to stay alive until you can combo off. If the combo is disrupted and the game goes into fatigue, Untapped Potential and Jade Idol combined should be to much for your opponent to handle
