@ Soliuz..haven't you ever experienced playing Uppers in ELO? or do you only play Type2?
IMO..Rubie is, first of all..only a 3star card (saves space)..she has SOA..she has -10 opp attack min 3..6 damage that can penetrate damage reducing abilities and reduce opponents life in half..8 damage if with fury..sure she only has 5 power (but who cares, she's proven to be ELO worthy)..all in all she's a decent 3star card for Uppers..
Judging by his elo score and the number of players his has won against... I have to say that he experienced elo quite a lot
but that doesn't mean that he is right, of course Rubie fells to many cards, even a power 7 card can defeat her without much trouble, but nevertheless 6 damage combined with SOA and a powerful bonus, all this at lvl 3, make Rubie a more than decent ELO card
