Worldslayer worm

[Destore117]

{Worldspine Worm} equipped with {Worldslayer}
Mana ramp like a boss
Oh hey your opponent has nothing left on field and you get 3 5/5s

[Nanocarter23]

Get two {myr galvanizers} and your set

[Stromack]

Or {knight exemplar} and {worldslayer} for 12 less mana lol

[Sardok]

{Knight Exemplar} isn't indestructible though. If you have no other knights in play, it's just a board wipe.

[Destore117]

If we're looking for cheap unblockables
Throw an {Invisible Stalker}
But you still want creatures and such
So somehow throw in an {Avacyn Angel of Hope} leave opponent's with nothing.
