This deck would cast Squandered Resources, sacrifice all lands to Natural Balance, then cast Cadaverous Bloom, and then pitch cards to generate mana and draw more cards
Here, since you have to tap to use it, and you only have 6 uses, I like it with haste in Red or equipment, untaps or haste like Thousand-Year Elixir and then after it's done, a blink effect like Momentary Blink
The deck revolves around casting an army of spider creatures and then using Shelob's ability to give your entire army deathtouch, ward 2 and most importantly effectively resuscitate your opponents' creatures as tokens
For example, if you control Elsha of the Infinite ("You may cast noncreature spells from the top of your library") and Keeper of the Crown is on top of your library, you can cast Coronation of the Wilds, but not Keeper of the Crown
In the eventuality any of your creatures dies, this powerful angel is ready to take things to the next level and burst your opponents (along with your other creatures) as it transforms into Avacyn, the Purifier
For just three mana, it gives you an immediate, instant-speed way to convert your tokens into advantage
