Not a token! You take a card out of your sideboard (in tournaments) or collection (in casual) that matches the characteristics and put it onto the battlefield. That card remains part of your deck for the rest of the game, even if it's bounced or destroyed. For example, this card can get Grizzly Bears, Druid's Familiar, or even Woodland Changeling.

Hmm, the colour stops it getting Clone Shell. Shame. Nice idea for an un-card.

The color and that Clone Shell isn't a bear. This should work in black-border, though. It's handled by the same rules as the Wishes or Spawnsire of Ulamog.

LOL. Yeah, it's a lovely idea even if it probably wouldn't be printed in a real set.

­Druid's Familiar is definitely the strongest, though you might occasionally want Ulvenwald Bear or Pale Bears.

Hahaha. This could be a lot of fun.

Predicted conjure over 8 years early

­Striped Bears is also sufficiently over the curve to be a consideration.

But it's kinda limits design space for cards like Udh, the Glacial and Wayo, Primordial Soup. :P
