TDS pairs multi-install with (multi-)draw.

The problem with exclusive multi-install effects is that you need enough installables in hand. For example, [[Shipment from MirrorMorph]] has an implicit Play only if there are at least 2 to 3 assets, upgrades, and/or agendas in HQ. gate. And if you do, you still need to refill your emptied hand.

Other “Clearance” effects that draw multiple cards (like Red Level Clearance) can still only install a single card. Fast Break is an exception, but with an implicit Play only if there are at least 2 agendas in the Runner's score area. gate.

However, TDS lets us multi-install from smaller hands (with sub-optimal installables, even with only a single installable pre-draw). And it refills our hand as it empties.

For example:

• Asset-Spam: Install two assets, while drawing one-or-two more. Like “DIY NEH”.

• Fast-Advance: Install a multi-clicker/multi-advancer/clickless-advancer (like Bass CH1R180G4, The Holo Man, or any “new Calibration Testing”), alongside a 3/2.

NB. This compresses "install clicks", but only breaks even on "units of value"): 2[$], [click], CARD → 2×Draw, 2×Install. (As @Krams says below.)

Flavor:

• Name: is a pun. Corporate headquarters plans out simultaneous construction projects ahead of time, which then join up; and building the space elevator from orbit downwards is literally the most "top-down" construction possible around Earth (any farther, there's no "up" or "down").

• Art: shows creepy–cute “bioctoroids”. Being in outer space, they feel like aliens (despite us knowing they're terrestrials and built by Haas-Bioroid). Likewise, Sacrifice felt like an alien monolith (despite us knowing that Weyland built it). While exploited as much as Turtlebacks, maybe they have more labor rights than other Bioroids (because of how hard to reach they are).
