Starurumon

Gabu shell with Beelstar shoved into it, if you get extremely lucky you can also pull off an OTK. Otherwise just play and keep discarding until you can play Beelstar as cheap as you want.

OTK explination:
You'll need WereGarurumon in play, swing and trash card from hand for unsuspend and if not deleted, swing again.
Now digivolve into WereGaruru X and trash two for the unsuspend and digivolve into MetalGaruru.
Then you can swing with Metal, trash one to unsuspend, swing again, evade for another unsuspend, swing again.
But wait, there's more! Now you just digivolv into MetalGaruru X for another unsuspend and swing for game.

Like I said, extremely lucky, you are hoping to not get deleted in sec checks or that you have Gabu X and/or Garuru X in the stack to help save the stack.
Metal Storm is a nice tech option to help get another unsuspend, but you give up targeting 7s to bounce.
