Setting this up unimpeded isnt always easy
That makes it a really great set to crack open and enjoy, which is always a nice bonus when a set is already so damned cool
I also really like the art for Cloak of Confusion, Gravebind and Songs of the Damned, which are all very pretty for completely different reasons
As a quick related aside, theres a common anti-Reserved List argument that most of these cards will hold their value even though a reprint because even if they print more Underground Seas, they arent going to print any more Beta Underground Seas
The former is the aspect in which the creature card known as the Grand Abolisher excels
No immediate payoff, no haste, no protection from removal, rather high cmc
