"Oh Yeah? My friends fight for ME."
Once again, I will not be stretching your mind with the gameplan here. Play Henzie, play your big folks, run them over. There are a few nuances though:
1. It is very easy to run out of cards in hand and very perilous to do so. It is critical to pace yourself until you can get Necro, Clamp, or Greater Good on board. Prioritize spending tutors to find them if necessary.
2. There's a pretty solid reanimation package and a decent amount of self-mill included in the deck. Use these to maximize early tempo by reanimating a fatty early on or to feed effects like World Shaper and Shigeki.
3. Malignus and Ghalta are simply huge beaters and nothing more, but combined with Xenagod, Ziatora, Selvala, or an opportune blitz, they can finish off opponents out of the blue. Use them judiciously, as playing them just to play them will quickly result in a dead fatty and 0 damage.
4. Shigeki and Sneak Attack can do some neat tricks together. " : Do Shigeki's thing" is a hell of thing to get rolling, trust me.
5. Requirements of a playable fatty may vary. Ideally, we want most of our fatties to be MV 4-6 and to have a beneficial triggered ability upon ETB or Death. But what those fatties need to do in order to be viable in your meta may differ from the list above. Swarmed with Token strategies? Bring in Havoc Demon, Magma Phoenix, Shard Phoenix, etc. Overwrought by Artifacts and Enchantments? Your answers may be Bane of Progress, Druid of Purification, and Acidic Slime. The deck has quite a bit of wiggle room in what fatties you choose so long as you maintain the critical mass of them, so flavor to taste!
