You start off with some early acceleration, generate some card advantage mid-game to keep the creatures flowing, and then close it out with Craterhoof Behemoth or some other trample effect
Once its flipped back over, you sacrifice it to Goblin Bombardment, dealing one damage to any target, and turning Ruthless Ripper back into a facedown Cyberman to repeat the cycle over and over until youre the last player standing
There isnt anything in the colors that gives all your creatures deathtouch, so well have to rely on something like Basilisk Collar, which can do OK on an active Keranos, Inferno Titan, or Hammerfist Giant
Elminster rewards you for scrying and can make little faerie dragons, Minsc & Boo can buff up a Boo hamster token and then sacrifice it for damage and card draw, and Tasha lets you cast other player's spells and creates demons when you do
