In Modern, Alpine Moon has the advantage of coming down two full turns earlier than Blood Moon (one of the problems with Blood Moon is that if you are on the draw and don't have any fast mana, your opponent can assemble Tron and play Karn Liberated before Blood Moon even hits the battlefield), although the combination of Blood Moon and now Damping Sphere means there is suddenly a lot of competition for the "hate on Tron" sideboard slot
Though the "True Draco" and "True King" Spell/Traps can support the "True Kings", they are only weakly supported by them
And you know what, they did
While theyre all eternal-legal, the set as a whole is clearly aimed at multiplayer Magic

If you're going to make a fancy play not mentioned above, set a stop or go into full control
