The basic premise of the card game is simple, players draw cards from their deck and play their Pokmon, trying to defeat their opponent's Pokmon, it seems simple right
If we look closely, we can see that all of the cards are marked
The one thing that bugged me, though, was that "enters the battlefield" effects didn't trigger when you phased back in
I think its likely that this will be one of the better blue commons as it fuels all of these archetypes
When this creature enters the battlefield, create that many tokens that are copies of it.) Menace (This creature can't be blocked except by two or more creatures.) Once you announce that you're casting Ruthless Radrat, no player may take actions until you're done casting it
Creating an online randomizer that lets Urza make his own choices about the spells he casts is a clever way of capturing this (if a little awkward in paper Magic for folks who, like myself, have been reluctant to join the smart phone generation)
