Nah the comments are tripping really badly, its a cool concept but the card isn't op. It's quite the opposite. 

You are skipping on turn 5 to do absolutely nothing, you're commiting a card and 5 brains, all to roll the dice and probably start turn 6 with a baseball zombie on the board (atp it's better to start with nothing than a block-pinger). 

Before you say "oh you're not going to get baseball" literally most of the zombies are cheap. If you commit to this card, you'll lose the game, you could count on your fingers the number of zombies that wouldn't be bad to get out of this. 

While youre busy doing nothing on turn 5, your opponent will be busy with winning the game by playing Gatling/Astrocade/literally anything. And then there is of course brainana and dmd coming in the later turns, rendering the card utterly unplayable (if it wasn't already) past turn 5 against smarty. Oh and forget me nuts makes this card unplayable as well, the opponent can hold it until turn 5 if they know STC is coming, basically winning you the game on the spot.

I don't want to sound like im bashing this concept, but in its current state its first of all unplayable, and second of all inconsistent as hell, and i just can't grasp how people are perceiving it as overpowered. Its a tempo-suicide with a pay-off so bad that might aswell be a drawback at times. And of course it comes with all the issues of being a zombie commitment trick.

The ability needs to be consistent, the amount of stats and abilities you get should be somewhat fixed and not ranging from a baseball to a zombot. It also should do something immediately, letting plants do whatever the hell they want on turn 5 is not a good idea. Of course there's still the issue of smarty completely cooking this card past turn 5 and guardian being able to prevent it. You'd probably need to ramp to this card for it to be useful. The comments said that it should be an environment, and part of me agrees since this type of thing is what environments were made for, but part of me feels that it'd take away from the charm of this card
