IMPerial March

IMPerial March is an 8 costing legendary sneaky zombie trick. When played it brings forth the wrath of Impfinity, who summons his hordes of minions. A random Imp class zombie is spawned in each lane, all of which do a bonus attack. For the graphics of the card it can be like Impfinity's "Triple Treat" trick, however with more imps and generic ones vs Impfinity clones.

This idea is kind of out of the blue, but I believe it would be a good addition to the game. A legendary trick that isn't absurdly expensive and can be used as a game changer, or as a safety net when all hope seems lost. This is my first attempt at making an card, so any suggestions are appreciated.
