There is a reason and that reason is cost.

If you can get the main benefit from critical damage on quick cards (i.e., Jack) then you can replace Gem Magecraft for 'near full effect' for 4 less cost.

Basically you can decide - +4 cost or +crit on Bust and Arts cards. Generally the latter is more favorable though.
