Baldin, Century Herdmaster is another card on this list that changes how damage is assigned, along with a solid way to pump the toughness of your creatures
This card plays beautifully with lifegain strategies as well as with white token duplicators such as Ojer TaqOjer Taq, MondrakMondrak and Elspeth, Storm SlayerElspeth, Storm Slayer
If I were to suggest 1 buff, maybe allow it to give effect destruction or targeting protection to your other Itsus
Last remark, I do not think anybody overrates tarmogoyf, I'd rather say too much people considers it to be weak in the cube, to the point of not maindecking it in decks in which it would perfectly fits in
