Drifter

Blue’s support cards are incredible in this set, but it does have a couple of big weaknesses: most of its creatures at Common are understatted and weak, and all its cards are a mixture of fliers cards and slow and defensive cards; those two factions don’t synergise amazingly. For those reasons, despite all its really high grades, I think it’s worse than it looks and you really need to lean on your second colour to have it reach its full potential. Blue’s power level is contained more in its uncommons than commons, since those are mostly completely absurd, probably the best in the entire set, but it also makes it a bit hit or miss. If you can support it well e.g. with big green creatures, black or red removal or in an Azorius dedicated cycling deck, Blue is going to live up to its ridiculous potential.The fliers deck is a bit more self contained, since Blue has all the tools it needs, but you do need to get the right half of Blue’s cards – the good blockers, the tempo stuff, and obviously good fliers rather than the cycling cards, medium counterspells, and slow Enchantments.

Blue has incredible potential and is likely to be one of the best colours, but it’s in an inconsistent fashion and I do caution a bit against overvaluing it, and being aware of and ready to mitigate its weaknesses.
