More cards are yet to be revealed, but this Secret Lair will be live on August 17
Magic Online shows us that if a draft format is really, really fun, players will play it even if the value is bad (see: cube drafts), assuming the entry fee isn't too high, but if the cost of entry is too high, players will shy away from the format even if its great (see: Masters drafts on Magic Online , which are often amazingly lacking in value, since the EV of Masters packs online is often around $2, while Wizards still charges $25 for a draft)
If a land has an ability that says it enters the battlefield tapped, you choose the order in which that ability's effect and Spelunking's effect apply
Its also a good fit for a pseudo-artifact-themed deck
Concluding Thoughts There are plenty of shells for Serendib Efreet to flourish in Old School 93-94, and this is merely one example, packing a bunch of the most efficient spells in the format, in a forward leaning aggro-control build
It wants you to ramp by using cards like PuPu UFO and Reach the Horizon to quickly put as many Towns as possible onto the battlefield
