Given that the set launches officially today, wed expect it to be popular in the coming days
It's Flying, so it's able to attack your opponents nice and easily over your opponents' blockers
But thats easily fixed with an extra spell or effect, turning it into a powerhouse on the battlefield
You only get to play those cards til the end of turn, which kind stinks, but its not a bad ability at all
Of course, its fine to make maindeck decisions that are influenced by a certain matchup (like Burn), so long as those decisions dont also hamstring you in other matchups
