I'll toss in my two cents about hammer/anvil units.
Lore of Life, Lore of Light, and Lore of Shadows ALL make Saurus Warriors shine.
Concerned about low initiative? Why you would be with an anvil is beyond me but if you truly detest striking last then play a different army.... I mean take Lore of Light. The REAL benefit this brings to the table is bumping our scaly brothers up to WS 10.. most things now rolling 5+ to hit makes for a tasty start for promotion into anvil status.. though this is actually my least favorite answer.. it is highly dependent upon one spell remaining on the field.
Lore of Life turns our fighting lines into juggernauts. Saurus suddenly boasting T 8 means 95% of the game are throwing 6's to wound. Ontop of this we have regrowth.. so even if something DOES nickel and dime some of these insanely tough models off the field we can bring them back. Couple that with shield of Thorns and you now have an anvil that is throwing 15 s 4 attacks up front, and 2d6 strength 6 attacks at EVERY unit in base contact at the end of EVERY magic phase. Lasting power, reasonable fighting prowess, and so many spells to deal with that the enemy will bogged down with A) preventing several amazing spells from hitting the field, and B) throwing their own power dice into dispelling to just have a prayer of taking down our forces. Magic dependant? Yes, but Focused Rumination means most of these spells only require ONE power die from our pool to cast/recast successfully.
Lore of Shadows is almost the opposite of Lore of Life as it turns our enemies into mush. The ability to, with various spells, reduce the following by d3: WS, BS, I, M, S, T. Ontop of this a spell that swaps out S for L when rolling to wound? Yeah, L of 8 means wounding on 2+ for a huge percentage of the warhammer world.
We have one of the most potent spell casters in the game.. the Slann packs one hell of a punch and is the backbone of any good Lizardmen army. Saurus warriors are one of the top contenders for stat lines vs. cost of any army. Bump them up with magic and they stand toe to toe with models 3-4x their cost.
