Any deck that uses a graveyard (which is quite a few in Casual Town) can use this as mainline card-draw spell
This can allow to either bait an interaction or search a Rank up magic to dodge targeted effects on your Xyz monsters, more on that in the Revolution Force build section
Depending on the value of the card and the prevailing market situation, we can either sell the card privately to a collector or take it to auction
To help you achieve this, Virtual World cards make up the vast majority of the deck
Eventually, you find some copies of Nettle Sentinel, which allow you to go infinite in mana, and more copies of Glimpse of Nature, so each Elf you cast is drawing you two, then three, and then four cards instead of just one
Id imagine thats what changed in the past handful of years
