Sailor Miles is focused on giving new players an extra bonus for buying cards. If a serious new player comes along and is going to drop $500-1000, which I see all the time, in all games, they will get a nice shiny new card as a bonus reward.
Older players mostly don't care about Sailor Miles because they have all or most of the good cards so opening Gem Packs would be redundant. Though some will open Gem packs here and there, for example today I have seen many veteran players open packs in hopes of new cards while also acquiring Miles for the long-term.
Also dropping $100-200 so one can acquire a guaranteed HP or Poison card.
