Banning Yookie won't hurt too much, Roots still have enough 3* to play, if you're hurt by the ban and feel like Roots cant be played now its proof that he was too powerful (which isn't true but still we can work around it)
Olga is a bit annoying since I love Freaks but she is actually very strong and like Roots they have enough 3* to cover, so it hurts but it's justified
Askai obviously needed this he was very very annoying, but I'd say Troompah is worse, either way good call
Azel I guess is justified, I personally haven't used her since 2010 but I know people do and her poison is quite large
Muze I see no problem with, I don't use her in my pussy decks but they were getting popular and Muze was getting annoying but even if she wasn't banned I wouldn't complain
And now for Robb Cr
He's a 3* surrounded by lots of great 3* and he's a cr so new players don't have him as much.... Why not ban Saki or Marina who actually make allstars hell to play against (or easy to win with) I don't see the point in this at all
People being hurt by a Yookie and a Muze ban, does not reflect the fact that he/she is powerful. It merely means they are decent options and without them you pretty much lose the point of playing, especially in the Roots.
Yes there are substitutes, but nothing makes a solid statement as a 3* as Yookie did. and you talk of powerful cards, there are always certain decent ones on which you base your deck. See, like Bangers have Beeboy, allstars have Marina etc. Yookie was one of those cards who made playing Roots a viable option. HE IS A CARD WHICH IS PRESENT IN EVERY SINGLE DECENT Roots DECK. You remove him, you lose the point of playing with Roots pretty much. Not completely, but Pretty Much.
