You want stat-boosting permanents on the battlefield as quickly as possible such as Soulcatcher's Aerie, Murmuration, and especially Coat of Arms which is the best typal-based stat boosting permanent in the game
Simply exile Spectral Deluge early in the game for 2 mana, wait several turns for your opponents to forget about it, then surprise them after youve built up some lands for a mere 3 mana, allowing you to follow up with a game winning card immediately afterward
My second turn is likely Opt, use Scalding Tarn, Serum Visions. Opt first, use that info to figure out what land I want on my fetch as the cost of reshuffling a bottomed scry is low,and then Serum Visions and get the maximum out of that scry
Auras arent naturally well-suited to Constructed, so it takes a particularly strong one to catch our interest
Even making just three tokens in a turn lets you dish out nine points of damage exceptionally quickly
