Well, like you said SG, I think people have different ideas about what is mindless. kobisjeruk says mindless is activating casting/activating anything that is blinking. I personally would agree with your definition more than kobi's. Mindless means looking at one thing, your cards. If it's highlighted click it. I add an extra thing to look at, your HP. Then you play highlighted cards if the HP condition is met. Yep, it requires two things to look at and then some "thinking". That's why I say it's
almost mindless. The only cards you have to "think" about are Sundials and Bone Walls. And really you're not even thinking, you're just checking to see if you have enough HP or not. The other cards can just be played when you have enough quanta. Sure, I give the optimal order to play them if you want to take the time, but it's not necessary.
And also, the vast majority of the time, the health check actually prevents you from playing Bone Walls over Bone Walls. Either they do their job and you regain HP over the 70HP and therefore don't play another one, or they fall quickly to all the AI's creatures and you play another one if your HP is lower than 70.
It might sound silly to some, but I take topic titles seriously because they are closely related to forum usability. If a title suggests something, then content should match, otherwise it's kind of tricking the user.
For example, lets say I title a topic "fastest deck ever". However the actual deck I post is very slow. Now the question is, can I keep that title even though it's incorrect? Can I use terms like "fast", "mindless", etc. in any way I want regardless of what my deck is like?
Not attacking you SG, but even you put up not quite accurate titles. For instance, your mono-Fire AI3 grinder is titled "Mindless Ruby Dragons -
fastest way to grind AI3" [emphasis mine]. But it's actually only the 8th fastest way to grind AI3 of all the tested decks. I don't think you have to necessarily change your title, but at least "almost mindless" is a little more ambiguous and therefore arguably accurate still.
About the deck.. have you tried a version with only 1 Bone Wall? That would make the deck more "mindless", and it would also drop the total card count to 30, making the deck faster. Then you could also drop some of the Towers and maybe take something else instead.
One option is to take both Retrovirus and Bone Wall because they have nice synergy.
I've considered a 30 card deck, but even with the 32 card deck, I've decked out sometimes and it's quite common to win with just a few cards left. That's why I left it at 32 cards. Retrovirus would work well with Bone Wall but then it would require more looking and thinking, not to mention a different kind of thinking.
I tried to think of different ways to make decks as fast and mindless as possible while still winning decently against HB. Unfortunately, with all their CC and huge HP advantage, you really can't go the creature-damage route very well. Obviously mono-Aether works fairly well against decks without PC. But even that you have to "think" about when to play Phase Shields. I suppose maybe a mono-Fire deck with unupped Phoenixes, SoGs, and Fire Shield might be feasible and pretty mindless. You'd still have to constantly check and revive any dead Phoenixes though so it's still not completely mindless.
