Whenever another creature or artifact you control is put into a graveyard from the battlefield, each opponent loses 1 life
Without any of the blue power supports (Thopter Spy Network, Prism Array, Part the Waterveil, yadda), I literally cant build a viable deck
TAHK0 speculated on why the error may have happened, writing, Poke Balls went through a lot of early variations, with everything from the button placement changing, to how it opens differing, to even being depicted with the white on top. It could be that an early Pok Ball design actually did open like it does on the card back, but when the design was eventually changed to the opposite way, they forgot to update it on the card back before going to print, and it remains that way to this day
Still, understand that each Set pack will give you at least one (and as many as four) rares and/or mythics
Until end of turn, those creatures can't become tapped unless they're being declared as attackers
