Mono blue in particular is very weak at the moment. Splashed with other colors it isn't so bad, but it's draw, counters, and creatures aren't half as good as they were last block.
Not sure what I'll do in standard. Haven't played since my kithkin pals rotated. I made a Green/White Deck with some ramp, knight of reliquaries, thornlings, and got 2 baneslayers, and some planeswalkers. But it still can't beat Jund most of the time so I haven't bothered going to tournaments with it.

The new planeswalker cards are treated as permanent spells that you control, they have their own type "planeswalker", and are not creatures, but considered players. Bottom right hand side will be a number, usually 3-4. Means it starts with that much "loyalty" aka life. +1: do this, -2: do this, -9: do this.
Add a loyalty counter to it, to get that effect. -2 counters, -9, etc. You can attack the planeswalker or your opponent with your creatures, but the opponent can block for the planeswalker.
