Since you yourself have active Unliving decks, for a good number of your games to have Unliving involved is only naturalo.o Why did you tell you have them?
A single personal experience doesn't change the overall trend, in any case. Your personal experience did, in the present case, skew your view the game at large. Look:
Non-Titan Unliving cards listed by rank in most played, at the time of post:14. Petrified minotaur, 15. Stone archer, 71. Golem messenger, 73. Flesh golem, 107. Crystal golem, 112. Spirit of Earth 121. Titan soldier, 125 Stone Atronarch, 128. Stone Gargoyle, 143. Bronze golem, 161. Stone golem, 167. Chaos gargoyle, 211. Mirror golem
Average Position: 111th, with 13 cards
Mage cards listed by rank in most played, at the time of post: 9. Acolyte, 21. Wizard, 27. Conjurer, 32. Fire Guardian 48. Warlock, 55. Chaos Wizard, 72. Elven Sorceress, 74. Librarian, 76. Druid.
Average Position: 46th, with 9 cards
Position of Unliving support cards: 130. Reuse the rubble, 250. Petrify.
Position of Mage support cards: 35. Mage Guild, 114. Wizard’s cottage 198. Devilkin, 235. Fireball, 240. Arcane bolt
Non-titans only since you aim to keep Titans in your hand; the less you have to play them, the better, and thus to include them would be unfair to Unlivings.
To reiterate:
1. After the two outliers practical in other decks, for 56 card ranks, Unliving is in a dead zone. The disparity between quality is huge, and by no means an accident.
2. A shameful 60% of non-Titan Unliving cards are above the 100th place. Compared to the Mage's Zero. There are no below average common Mages. None. There aren't even mediocre ones. They are good all around.
3. Unliving have better potential for variety, but the potential is untapped and Mages are far better in the regard than they are. Mages have less cards with varied card effects and keywords, are thus simple to combine with other keywords to great effect. Unliving have more cards who do more of the same, each of them are thus played less.
4. After everything above, Mages are more popular by 65 ranks.
Just the Common ones were listed, for your sake, since from Uncommon up, Unliving's case is even worse, with no Petrified minotaur or Stone archer equivalent to save them a little face.
Mages are not only more popular than Unliving, they are more popular to an extent visible to the naked eye. Decks are less often Unliving decks than they are not at all with a few slim picks from the good to decent ones. Mage decks are simpler to construct, simpler to play, and have wonderful variety in keywords and effects, and thus better for combinations overall.
The fact is. GreenEmerald. Unless you say the vast majority are happy to lose their games just for the chance to play the more popular mages, you have an ill-constructed Mage deck. Commiserations.
You have two great Unliving decks however! They are almost one of a kind, too:3 Even should you be correct on the matter of quality, Unliving need a little variety and popularity regardless of how good they are. But, while the 65 rank difference average is not proof mages are also better in addition to a fan favourite status, you dance on a sharp Occam's Razor when you claim otherwise.
