New Redemption Grab Bag now includes an assortment of 500 cards from five (5) different expansion sets. Available at Cactus website.
Speed decks don't really need to change much if at all. I don't play mine very often but it still wins when I do and most of the time by a large margin of victory. Everything RoA introduced that might hurt speed can be worked around if you play your cards right. If a person packed a deck full of cards to hurt a multicolor offense and/or defense they'd get pwnd by all the mono color decks running around since RoA.
If this was a year ago, I'd make some great comment about MASK.
