Toss in a Candelabra of Tawnos and your opponents might as well concede
It weakens all of those creatures until your next turn, so you can take advantage of their lower power so that you can attack on your turn, and then also benefit from the fact that your creatures cant attack as hard

Do make sure to note that Imposter Mech can only copy an opponents creature, which prevents crazy Sharuum, the Hegemon loops

It can also be built as a mono-blue deck, sporting more Boomerangs, and things like Unsummon and Time Elemental main deck
