The tribal push is good with the problem of the various energy decks being able to slot in the best card(s) from a new set, as happened with
glorybringer, scarab god,
carnage tyrant. Say a new card is just 'decent', a playable card that needs tribal support - which is tough to impossible for energy decks as they need energy cards, and those energy cards are 4 or 5 different creature types none of them pirate, vampire, merfolk, or dinosaurs - and those new 'decent' cards get
a lot better with tribal backing. I like it.
If they didn't put in another answer for energy, this at least stops energy decks from cherry picking each set to get even more dominant.
