Re: The Imps have broke Gnome Bomb
There are actually a number of abilities which can disrupt attempts to defuse the Gnome Bomb; EMPeach, Goatify, and Time Snare on the Plant side can all cause interference.
If you're in a game where Imps are stacking Gravity Bombs on the Garden when the Bomb has been set then the Plants can give them a taste of their own medicine by having Citrons stack EMPeaches the same way when the Bomb has been set on a Graveyard.
