we would expect to see three radically different sets of cards more often.
This is exactly what happens
. It's called confirmation bias:
http://en.wikipedia.org/wiki/Confirmation_biasYou see bone wall twice in one set of spins, and your brain is automatically making that stick out and you're forgetting all those times that that doesn't happen.
Either that or it's just the inept flash random doing its thing again.
Oh, and I just played some games vs. AI 5:
Spin 1: Upgraded Vamp Dagger, unupped Vamp Dagger, unupped Vamp Dagger
Spin 2: Black Dragon, Dusk Shield, unupped Vamp Dagger
Spin 3: Liquid Shadow, Devourer, Parasite
Spin 1: Plague, Plague, Boneyard
Spin 2: Graviton Mercenary, Momentum, Graviton Mercenary
Spin 3: Graviton Mercenary, Aflatoxin, Colossal Dragon
Spin 1: Upped Aflatoxin, Aflatoxin, Upped Aflatoxin
Spin 2: Plague, Upped Quintessence, Plague
Spin 3: Virus, Dim Shield, Virus
Spin 1: Black Hole, Black Hole, Black Hole
Spin 2: Upped Momentum, Upped G-Force, Cockatrice
Spin 3: Black Hole, Black Hole, Black Hole
(Poison AI3 - Keep in mind it has a much smaller card pool)
Spin 1: Blue Crawler, Blue Crawler, Poison
Spin 2: Freeze, Arctic Squid, Arctic Squid
Spin 3: Ice Shield, Poison, Ice Shield
In effect, these prove nothing
. The fourth game looks odd, but when you consider black hole need only be 1-3 of those slots, it may not be. Also note that we aren't sure of the AI5's exact deck make up so the statistics could go either way anyway.
But I'm almost certain that I'm right.
