On the new-card side, Shard of the Nightbringer is the one people want, an 8/8 flyer that drains half a players life when it lands, with Biotransference and Their Name Is Death rounding out the flavor-meets-function picks
That draw trigger isnt just flavor text either
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
Now, Valgavoth does come with flying which is important for evasion to hit your opponents and for potential blocks
This allows you to bypass the "commander tax," as you aren't casting Derevi and the additional cost will not be applied
This is in order to keep things moving at a reasonable pace and not hold everyone up
