the thing is, O2’s intended best-case use isn’t anything you can really build a deck or strategy around.
Damon himself said that he could see moments in the game where the runner really wouldn’t want to lose a particular card in their hand, and he could always use an extra click
honestly, the only time i could see this having any use is to bring them down to -1 cards with Scorch/Boom!/etc., and if they give you the extra click, Archives > Scorch or something
trying to snipe the I’ve Had Worse doesn’t work because 1) you could very easily miss, 2) it wouldn’t help you kill them anyway unless you had extra kill cards in your hand, which you should have just played anyway, 3) Salem’s is way better anyway
this card’s intentionally-designed best-case scenario is just waiting for a moment when you think the runner might have something they don’t want to lose and thinking ‘i can always use a click’ while also thinking ‘3 credits isn’t that much for an extra click to just install something or draw a card’
