Pseudo-RNG. It's meant to avoid strings of lucky crits, though. So if you have 50% crit and just critted twice in a row, you're less likely to crit on the next attack. And vice versa: if you have 50% and didn't crit for two attacks, you're more likely to crit on the next. 4 or 5 in a row with just the Ghostblade crit chance is therefore meant to be pretty unlikely... my guess would be that the pseudo-RNG is on a per-target basis so you can't abuse it by AAing minions and not critting then hitting your lane opponent for a high chance of a crit. It's still not likely to happen if that's the case, but it could happen frequently enough for you to notice it?
