After playing so much I am close to certain that playing 29 lands is right if you build your deck correctly it doesnt really happen that much that you just simply flood out or dont have a card in your deck that you need as explained but you can EASILY lose if you dont have lands the deck is extremely mana hungry and all the Scry Lands make sure that you DO draw that needed Krasis or Trawler so I just think that having bunch of lands is the way to go
This, of course, is a costly loyalty ability, but Vraska has plenty of other value to offer
Sure, there are still 28 red energy cards and another 22 colorless ones you can include in a Motherlode deck, but it just wont hit the same as an energy deck with access to Bristling Hydra or Razorfield Ripper
Undying is a keyword that brings dead creatures back to the battlefield with a +1/+1 counter if they died without one
