“Draining” multiple credits, Transfer is a “(mini) Siphon reborn”!

• It can be a nine-credit swing (their -3[$] into your +6[$]), and you still breach HQ.

• Even as a six-credit swing, and with an op/ice accessed, it's bounce-back econ with econ-denial. For example, if you detag ASAP (minus your -2[$], [click]), or if the Corp rezzed down to two credits mid-run (their -2[$] into your +4[$]).

Until release, see the reviews on Diversion of Funds and Account Siphon for the general strategy/behavior.

Flavor-wise, money has diminishing-returns of utility: each credit is worth more value for the less rich (Runners) than for the richer (Corp).
