Mushroom?

Mushroom? is a Token Plant in Plants vs. Zombies Heroes and a member of the class. One can be gained or shuffled into your deck from Zombotany S.Q.U.A.D.. It costs 4 to play and has 2/2. Its ability while in your hand makes all other non-? cards unplayable until you play them all, including this card, and it will do 1 damage to all Plants in play, including itself.

Origins
It is based on Button Mushroom, the basic plant of the Smarty class, and a Backup Dancer disguised as a Button Mushroom. This may be because of the fact that the two classes have similar play styles (i.e. damaging cards, spamming, and strength boosting).

Card description
Something's hiding under that cap, but it's not a Mushroom...

With
Although this card might not be so threatening, it still can destroy any of your cards that has 1, and it's also enough for the other Hero to use a damaging trick or raw strength to destroy a Plant. Also note that they might have Zombot Sharktronic Sub on the field, since both Zombotany S.Q.U.A.D. and Zombot Sharktronic Sub are in the Sneaky class, and Beastly Heroes, namely Brain Freeze, can use Zom-Beekeeper to destroy your Plants as well. You can also do more damage to your Plants if you have some Binary Stars in play.

Against
Mushroom? by itself isn't much of an issue, but against the wrong kind of deck, it can be worse news for you. Mirror-Nut can benefit from himself and his Nut friends being hurt, and Punish-Shroom can benefit from having him and other Mushroom Plants destroyed. There are other Plants that benefit from getting hurt or destroyed as well, such as Flormonger and Potato Mine.
