I hesitate to call it the best board wipe in EDH, but its role as a catch-up tool and win condition lands it in the top 5 at least
These three cards care about making tokens and killing non-tokens, helping you make a big board and prevent your opponents from doing the same
there are better ways to draw cards for five or six mana, except maybe in mono white
It also makes all of your planeswalkers pretty insane, as they are often able to enter the battlefield with enough loyalty to fire off an ultimate right way
You'll have to cast a few creatures with greater power than one, then two, and maybe even three, but once you do, Pollywog Prodigy is going to start drawing cards like it's going out of style
I seriously hope that this was a one-off schedule from Wizards of the Coast and that it doesn't become the norm for how new sets are introduced to players
