Gameplan Hypergenesis is worded such that we put creatures, lands, artifacts, or enchantments into play
You tap it, untap it, tap it, untap it, and finally tap it again to tap all creatures with globe counters on them
With Underworld Breach out, keep casting Mana Geyser or Lion's Eye Diamond as ramp and a Wheel of Fortune or Collective Defiance to fill your graveyard, though Mana Geyser requires your opponents to have enough lands tapped and Collective Defiance requires you to have enough cards in hand to replace what you spend on Escaping
There can be delays if the package gets held up at customs for a time
With enchantment cards, Manifest Dread, and various other ways to enable graveyard filling, there will be lots of opportunity to benefit off Delirium in this set
White has struggled in recent years to get stronger at the same rate as other mana colours in Magic: The Gathering, so it's nice to see a few incredible cards there
